This is a port of a gitea PR: https://github.com/go-gitea/gitea/pull/34512. I have added some copy-editing commits on top for cleanliness. I haven't tested the changes manually and only relied on the existing automated test. ## Checklist ### Tests - I added test coverage for Go changes... - [x] in their respective `*_test.go` for unit tests. - [ ] in the `tests/integration` directory if it involves interactions with a live Forgejo server. ### Documentation - [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change. - [x] I did not document these changes and I do not expect someone else to do it. ### Release notes - [x] I do not want this change to show in the release notes. - [ ] I want the title to show in the release notes with a link to this pull request. - [ ] I want the content of the `release-notes/<pull request number>.md` to be be used for the release notes instead of the title.
