    wifi: Add padding to Known Wi-Fi Networks dialog
    
    The "Known Wi-Fi Networks" dialog is missing some padding to really
    make it look polished.
    
    By switching from a normal dialog to an AdwPreferencesWindow, we can
    take advantage of libadwaita's automatic padding.
    This will make sure the dialog is more in line with the rest of the
    GNOME ecosystem.
    
    Closes https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/1956
