Don't create duplicated functions for code repositories and wiki repositories (#33924)

Fix
https://github.com/go-gitea/gitea/pull/33910#pullrequestreview-2688913865

This PR changed the Repositroy interface in `gitrepo` package which
makes it only focus the relative path in the disk and abstract whether
it's a wiki repository or not.
