JSON:API now supports version negotiation on all versionable entity types

Before this change, version negotiation was only possible on node and media entities. Since we have added #3043321: Use generic access API for node and media revision UI we can now support other entities also.

After this change jsonapi now checks if an entity type is revisionable and then supports version negotiation on those entities using the resourceVersion query parameter.

If you maintain a content-entity providing module and would like finer grained access control to revisions, see the change notice for #3043321: Use generic access API for node and media revision UI.
