Remove gh-pages branch
The gh-pages branch in the repository causes this site to appear: https://pipewire.github.io/pipewire/ It's very outdated and probably should be removed. It might also need to be manually removed on Github side https://github.com/PipeWire/pipewire, not sure how the mirroring there works.
There are also other obsolete branches in the main repository https://gitlab.freedesktop.org/pipewire/pipewire/-/branches/stale
