Remove persistent LDAP volumes so bootstrap.ldif always applies on startup

The osixia/openldap image only runs bootstrap LDIF when the database is
empty. Named volumes (sail-ldap-data, sail-ldap-config) caused changes
to bootstrap.ldif to be ignored after the first run. Removing these
volumes ensures the test LDAP directory is always seeded fresh from the
bootstrap file on each sail up.
