Redirect mutter.gnome.org elsewhere
Currently, mutter.gnome.org points to the gitlab pages deployed from https://gitlab.gnome.org/Teams/Websites/mutter.gnome.org and we would like to replace that with the ones deployed from the mutter project, https://gnome.pages.gitlab.gnome.org/mutter/. Currently that page contains nothing, but it will soon once we merge GNOME/mutter!3490 (merged).
