[nautilus/wip/antoniof/gtk4-preparation-discontinued-api] toolbar: Don't rely on ::toggled in GtkMenuButton

[António Fernandes <antoniof src gnome org>]

    toolbar: Don't rely on ::toggled in GtkMenuButton
    
    In GTK 4, GtkMenuButton is not a subclass of GtkToggleButton, so it
    won't inherit this signal.
    
    Instead, listen to :visible in the popover.
