Update all edx-platform REST endpoints to support JWT Auth (#34152)

* chore: update API endpoints to support default JWT auth

The default DRF Auth classes were recently updated to allow for both JWT and Session auth by default. Any endpoint that overrides the AUTHENTICATION_CLASSES but has just session, just JWT or just both of those should be updated to remove the override.
