    gs-details-page: Re-position the buttons and the source chooser in the narrow mode
    
    Let the buttons with the source chooser be below the app name in the narrow mode.
    Also use a smaller gap between the buttons and the source chooser.
    
    Closes https://gitlab.gnome.org/GNOME/gnome-software/-/issues/1851
