wiki: point links at the public GitHub repo, not the private Forgejo host The wiki is a separate repo from the code and still carried forgejo.nielsbox.cc links (repo/architecture/build-plan/distribution/contactsheet + the 4 screenshot image sources). On the public GitHub mirror those broke and leaked the private host — matching the README, they now use github.com / raw.githubusercontent.com.
