Ship own/more recent Pipewire version
Over the recent months Pipewire got notable improvements for camera support, both in its core part and the gstreamer element, which are required for a good camera experience - especially on mobile devices. With more apps picking up xdg-portal+pipewire support, it would be great if they could benefit from new features and bug fixes, without having to wait for the 23.08 fdo-runtime update or having to ship their own version.
Some of these features require ABI/API breaks and thus can't be backported into the fdo-runtime. Therefore it would be great if the gnome-runtime could ship a recent version in releases, as well as tracking newest versions in nightly.
