    application: Use Gtk.FileChooserDialog for Flatpak
    
    File chooser portal right now can only mount one file, which prevents
    multi-file games from working. So let's use regular file chooser for now.
    
    Prevents games on external drives from being added, that will be solved in
    the following commit.
