[nautilus/wip/antoniof/gtk4-preparation-popovers: 3/6] notebook: Set action on close button

[António Fernandes <antoniof src gnome org>]

commit 56824dc3a8016106078ee8848d8d56a0e65f5abf

    notebook: Set action on close button
    
    We listed to the button's "clicked" event and emit "tab-close-request",
    which NautilusWindow listens to and closes slot in response.
    
    Instead, we can make this a lot simpler by setting the equivalent action
    and removing the signals glue.
