site-wide: Generate site content with a maintenance script.

When OVN 23.09 is released, we also will begin making more frequent point-releases of all other supported branches. Updating the website by hand for each release would be time-consuming and error-prone. This change uses a website update script to generate the website content. The script can be used for generating content for a new release or for updating content for previous releases, since the script re-generates content from scratch instead of actually updating the content.

+
+Release Notes:
+```
+OVN v22.03.1 - 03 Jun 2022
+--------------------------
+   - Bug fixes

+v22.03.0 was released on 11 March, 2022.
+
+[Github link](https://github.com/ovn-org/ovn/releases/tag/v22.03.0)
+
+Release Notes:
+```
+OVN v22.03.0 - 11 Mar 2022
+--------------------------
+  - Refactor CoPP commands introducing a unique name index in CoPP NB table.
+    Add following new CoPP commands to manage CoPP table:
+    - ovn-nbctl copp-add <name> <proto> <meter>
+    - ovn-nbctl copp-del <name> <proto>
+    - ovn-nbctl copp-list <name>
+    - ovn-nbctl ls-copp-add <name> <switch>
+    - ovn-nbctl lr-copp-add <name> <router>
+  - Support version pinning between ovn-northd and ovn-controller-vtep as an
+    option. If the option is enabled and the versions don't match,
+    ovn-controller-vtep will not process any DB changes.
+  - When configured to log packtes matching ACLs, log the direction (logical
+    pipeline) too.
+  - Introduce exclude-lb-vips-from-garp in logical_switch_port column in order
+    to not advertise lbs VIPs in GARPs sent by the logical router.
+  - ACLs now have an "options" column for configuration of extra options.
+  - A new ACL option, "log-related" has been added that allows for reply and
+    related traffic to be logged for an ACL in addition to the traffic that
+    directly matches the ACL.

+--------------------------
+  - Support IGMP and MLD snooping on transit logical switches that connect

+Release Notes:

+OVN v22.09.0 - 16 Sep 2022
+--------------------------
+  - ovn-controller: Add configuration knob, through OVS external-id
+    "ovn-encap-df_default" to enable or disable tunnel DF flag.
+  - Add option "localnet_learn_fdb" to LSP that will allow localnet
+    ports to learn MAC addresses and store them in FDB table.
+  - northd: introduce the capability to automatically deploy a load-balancer
+    on each logical-switch connected to a logical router where the
+    load-balancer has been installed by the CMS. In order to enable the
+    feature the CMS has to set install_ls_lb_from_router to true in option
+    column of NB_Global table.
+  - Added nb_global IPsec options ipsec_encapsulation=true (libreswan)
+    and ipsec_forceencaps=true (strongswan) to unconditionally enforce
+    NAT-T UDP encapsulation. Requires OVS support for IPsec custom tunnel
+    options (which is available in OVS 3.0).
+  - Removed possibility of disabling logical datapath groups.
+  - Removed the copying of SB's Chassis other_config into external_ids.
+  - Added MAC binding aging mechanism, that is disabled by default.
+    It can be enabled per logical router with option
+    "mac_binding_age_threshold".
+  - If it is needed to create Load Balancer within LR with VIP, which matches
+    any of LR's LRP IP, there is no need to create SNAT entry.  Now such
+    traffic destined to LRP IP is not dropped.
+  - Bump python version required for building OVN to 3.6.

+  - Add support for remote port mirroring (Experimental).
+  - Add new OVN IC Route table index. This index ensures no duplicate routes
+    can be advertized.  When upgrading to this version user must ensure that

+    database schema is converted.

+Release Notes:
+```
+OVN v23.06.0 - 01 Jun 2023
+--------------------------
+  - Enhance LSP.options:arp_proxy to support IPv6, configurable MAC
+    addresses and CIDRs.
+  - CT entries are not flushed by default anymore whenever a load balancer
+    backend is removed.  A new, per-LB, option 'ct_flush' can be used to
+    restore the previous behavior.  Disabled by default.
+  - Add support to configure OVSDB inactivity probe interval for ovn-ic and
+    ovn-controller-vtep.
+  - Add LS.other_config:broadcast-arps-to-all-routers. If false then arp
+    requests are only send to Logical Routers on that Logical Switch if the
+    target mac address matches. Arp requests matching no Logical Router will
+    only be forwarded to non-router ports. Default is true which keeps the
+    existing behaviour of flooding these arp requests to all attached Ports.
+  - Always allow IPv6 Router Discovery, Neighbor Discovery, and Multicast
+    Listener Discovery protocols, regardless of ACLs defined.
+  - Add IPv6 iPXE support introducing "bootfile_name" (59) and
+    "bootfile_name_alt" (254) options to ovn dhcpv6 server.
+  - Support using local OVS port as port-mirroring target, and also support
+    'both' directions for the 'filter' field.
+  - Increased ovn-{ic-,}{n,s}bctl default OVSDB inactivity probe interval from
+    5000 ms to 120000 ms to give the ability to connect to large databases
+    (mainly, OVN_Southbound).  Also, for daemon mode it is possible to
+    configure inactivity probe interval via OVN_Northbound and OVN_Southbound
+    databases for ovn-nbctl and ovn-sbctl respectively.  See man ovn-nb and
+    man ovn-sb for 'nbctl_probe_interval' and 'sbctl_probe_interval'
+    options for more details.
+  - Rework OVN egress QoS implementation in order to rely on OvS interface
+    instead of directly running tc from OVN. Get rid of traffic shaping on the
+    tunnel interfaces. Now for LSPs running on a LogicalSwitch with a localnet
+    port is possible to define QoS rules to apply to the local egress localnet
+    port. Please note now the QoS will be applied just to the local localnet
+    port and not to all localnet port marked with ovn-egress iface.
+  - Support for tiered ACLs has been added. This allows for ACLs to be layered
+    into separate tiers of priority. For more information, please see the
+    ovn-nb and ovn-northd manpages.
+  - Send ICMP Fragmentation Needed packets back to offending ports when
+    communicating with multichassis ports using frames that don't fit through a
+    tunnel. This is done only for logical switches that are attached to a
+    physical network via a localnet port, in which case multichassis ports may
+    have an effective MTU different from regular ports and hence may need this
+    mechanism to maintain connectivity with other peers in the network.
