    application: Use GNetworkMonitor::connectivity instead of can_reach_async()
    
    can_reach_async() doesn't seem to work well from a Flatpak.
    Relying on the connectivity property should be enough, and also should
    handle the captive portal case (if the user's system has enable
    captive portal detection in NetworkManager).
