[bitnami/openldap] Add documentation for OpenLDAP directory persistence

[najose]

Name and Version

bitnami/openldap (all versions)

What is the problem this feature will solve?

I could not find documentation regarding persistence of data for the OpenLDAP container. The examples seems to use /bitnami/openldap as the mountpoint for data volumes. Looking at the Dockerfile, there seems to be the LDAP_VOLUME_DIR environment variable which also points to this same path. Is the recommended path if so, can this be added to the docs. I can work on adding it the docs if it will be accepted after a review.

containers/bitnami/openldap/2.6/debian-12/rootfs/opt/bitnami/scripts/libopenldap.sh

Lines 35 to 36 in b423ff5

	export LDAP_VOLUME_DIR="/bitnami/openldap"
	export LDAP_DATA_DIR="${LDAP_VOLUME_DIR}/data"

What is the feature you are proposing to solve the problem?

Document the path where LDAP data is persisted.

What alternatives have you considered?
