[API] Only Return Json (#13511)

* Let Branch and Raw Endpoint return json error if not found

* Revert "RM RepoRefByTypeForAPI and move needed parts into GetRawFile directly"

This reverts commit d826d08577b23765cb3c257e7a861191d1aa9a04.

* more similar to RepoRefByType

* dedub-code

* API should just speak JSON

* nice name
