Continuation of #2444, which introduced the commit bf7fb89178f41c712b8a8863667a442ec1e1c5d4 but only added the label and the tests. The tooltip explaining what AGit is and its advantages is not meant to advertise AGit - it is meant to inform the reader that is presumably not familiar with the workflow that they will not be able to find a fork or a branch associated with the Pull Request as a direct consequence of this workflow. Issue #2474 mentions that we should show instructions on how to fetch an AGit-created Pull Request, and this is the plan. However, this may take time, so I might as well make the label a bit more "complete" and less out-of-place for now if we do not manage to improve these instructions until the next release (Forgejo v1.22).
