!Friendica Developers

Hi, I'd like to add a new domain `docs.friendi.ca` where we store the whole documentation. It should be versioned, like https://docs.friendi.ca/2022.09/ for the docs of the stable 2022.09 version or https://docs.friendi.ca/develop/ for the docs of the develop branch.

I think it would be possible to automatically generate it.

But before, I do need the domain - pinging @Michael Vogel - and a routing to the current files.friendi.ca vm-instance - pinging @utzer ~Friendica~ 😀

I'd like to generate it automatically during the CI, so the update would be smooth and automatically 😀
