    event_actions: Use GtkFileChooserNative for saving
    
    Fractal does not have a full view of the filesystem, which
    means that we can't use GtkFileChooserDialog if we want users
    to be able to save anywhere. Instead, we need to use the
    file chooser portal via GtkFileChooserNative.
    
    Closes https://gitlab.gnome.org/GNOME/fractal/-/issues/1064
