Consider shipping `phosh-portals.conf` for compatibility with xdg-desktop-portal-gnome >= 44
Since GNOME/xdg-desktop-portal-gnome@deae6336 xdg-desktop-portal-gnome needs "org.gnome.Mutter.ServiceChannel"
that phosh does not implement. So the GNOME portals don't work, and due to previous limitations in xdg-desktop-portal, the gtk fallback cannot be used. That changed in xdg-desktop-portal version 1.17.0, that allows to set a default, so that Phosh can ship a file that takes care of it. We are carrying the file downstream not sure if you want to have it here, but opening the issue just in case.
