Even though the OrphanVersionCleanupListener.java remains disabled in orphanVersionsCleanup-listener-contrib.xml since (NXP-24819), we should make it use the new BAF implementation (from NXP-27139) to clean up orphan versions
Moreover, GarbageCollectOrphanVersionsAction throws an IllegalArgumentException if the document is not a version and will make the action in failure after the retries.
We should just log a debug and continue for such trivial unexpected entries.
