refactor: Use new model instead of tags for Release Programming Languages

[Karthik99999]

comses/planning#259

Draft for now, still need to figure out making the release edit form actually submit (probably has something to do with the serializer) as well as making sure the migration works properly in converting tags to the new model.

Thanks @Karthik99999! Failing e2e test probably needs to be updated:
