Explore adding a test for Protected Branches API
The Protected Branches API has had some issue raised about it's performance (gitlab-org/gitlab#235461). While the specifics suggest this may be nothing to do with testing the endpoint at scale it's still not performing well at all in certain conditions it seems.
Task is to explore if we can add this endpoint in GPT. It may be best suited as a scenario. The linked issue suggests though a large number of MRs or a CODEOWNERS file may be the specific cause of the problem.
