Host the action on Gitea

Workflows move to .gitea/workflows, which Gitea prefers over
.github/workflows when both exist.

GitHub Actions can only resolve `uses:` against github.com, so the
README now spells out both forms: the full Gitea URL, and the
checkout-then-`uses: ./` fallback for a GitHub workflow that has no
mirror of this repository.
