Gitea 1.19.4 patch update. Release notes can be found at:
https://github.com/go-gitea/gitea/blob/v1.19.4/CHANGELOG.md
There are no breaking changes listed since the 1.19.3 we're
currently running, but one minor security improvement which is
basically not relevant to us, as well as a number of bug fixes some
of which may be (I skimmed and don't think any are but can't be
certain). Mainly this merges one template update to keep our forked
templates in line with upstream.
