[nautilus/wip/antoniof/gtk4-preparation-discontinued-api: 2/19] properties-window: Add discoverable Forget action




commit 9cc962b1aeff52158ab15b40e3cbc79e172cd288
Author: António Fernandes <antoniof gnome org>

    properties-window: Add discoverable Forget action
    
    The "Forget association" action is found in a single item context menu
    in the Open with tab of Properties window.
    
    Single item context menus are discouraged design and the feature is
    not discoverable. Other actions have buttons.
    
    Furthermore, this is implemented using two GTK features that are gone
    in GTK 4: GtkAppChooserWidget::populate-popup and GtkMenuShell.
    
    Just add a button instead. This is due a redesign later anyway.
