This PR adjusts the repository README discovery logic to mirror GitHub's
priority order, while retaining support for Gitea's specific `.gitea/`
directory.
Previously, Gitea would prioritize a `README.md` at the root of the
repository over any READMEs in `.gitea/` or `.github/`. With this
change, well-known subdirectories are evaluated first when viewing the
repository root.
**New Priority Order:**
1. `.gitea/README.md`
2. `.github/README.md`
3. `/README.md` (root directory)
4. `docs/README.md`
This allows repository maintainers to use `.github/README.md` (or
`.gitea/README.md`) as the repository homepage without having to remove
or rename generic root `/README.md` files required by package managers
(like NPM, Crates.io, Docker, etc.).
