If a repo has been tagged with gitea-pages-allowall we don't need an
extra gitea-pages branch with a toml configuration.
This makes it easier for repos that can just expose every branch
If we have a domain configured eg giteapages.io then besides the normal
user.giteapages.io and org.giteapages.io we also support
repo.user.giteapages.io / repo.org.giteapages.io
branch.repo.user.giteapages.io / branch.repo.org.giteapages.io
