    shell: Set hide-on-close to TRUE
    
    We want the main Software window not to be destroyed when it's
    closed. For some reason, up to GTK 4.4, GTK4 was lenient with
    not setting this property, but with GTK4 >= 4.5, we're not so
    lucky, and Software just stops showing its main window after
    closing it for the first time.
    
    Set the hide-on-close property to TRUE in GsShell. This should
    not change Software's behaviour on GTK 4.4, and only affects
    GTK4 >= 4.5.
