🪟🐛 [Connector Builder] Fix manifest conversion bugs (#21828)

* add check for undefined auth type

* fix authenticator equality check and add test

* don't allow nested objects/arrays in refresh_request_body and add test

* explicitly do not use refs in json -> yaml dump

* ensure the CheckStream configuration always has valid stream names

* throw on any non-string value
