make the gtk website ready for gtk4
Things that will need updates:
-
https://www.gtk.org/docs/apis/ - figure out how to show gtk3 and gtk4 docs in parallel, for gtk4, add gsk -
https://www.gtk.org/docs/architecture/ - same, for gtk4, replace cairo with gl, demote gdk-pixbuf -
https://www.gtk.org/docs/installations/ - same, show gtk3 and gtk4 in parallel
We probably want some visible update on the frontpage too (maybe https://gitlab.gnome.org/Infrastructure/gtk-web/-/issues/61)
