Ubuntu: bump OVN packages

The OVN packages in Ubuntu Yoga UCA repository are quite old - 22.03.
This version does not work with OVN native DHCP for external (bare
metal/SR-IOV) ports. We see the following warning in OVN controller
logs:

  Syntax error at `next_server' expecting DHCPv4 option name.

Pull in these packages from the Zed UCA, which are 22.09, to more
closely match the CentOS packages.
