DOCS-7429: Schema Registry Ranger Policy requires schemaregistry group in Ranger Admin

Schema Registry fails to start because the schemaregistry user group does not exist in Ranger. The following message appears: Operation denied. Group name: schemaregistry specified in policy does not exist in ranger admin.

Ensure that the schemaregistry user group exists in Ranger. Depending on the environment settings, this might require manual creation of users/groups and/or re-configuration of the usersync/groupsync filter in Ranger.
