- When there's a succesful POST operation, it should return a 201 status
code (which is the status code for succesful created) and additionally
the created object.
- Currently for the `POST /repos/{owner}/{repo}/tags` endpoint an 200
status code was documented in the OpenAPI specification, while an 201
status code was actually being returned. In this case the code is
correct and the documented status code needs to be adjusted.
- Resolves#2200
