[pve-devel] [PATCH installer] fix #4643: show a confirmation dialog when clicking abort

Note that unlike the rest of the file, we connect to the response signal
instead of using Gtk3::Dialog->run, the reason is that run blocks the
main loop used by GTK and this undesirable to the point where
Gtk3::Dialog->run was removed for GTK 4.
