Add worker_version=false option on ListTranscriptionEntities

Refs https://gitlab.com/arkindex/requests/-/issues/133#note_1012291356

For consistency with ListElements, ListElementParents, ListElementChildren, DestroyElements, DestroyElementParents, DestroyElementChildren, and ListTranscriptions, the worker_version filter on ListTranscriptionEntities should allow both a worker version ID, or false for no worker version.
