fix: Adapt 'About' menu path for GNOME 46.

[hirnidrin]

There was some Settings menu mangling from GNOME 45 to 46. In GNOME 46, "Logomenu > About My System" fails to open the "About" detail window, instead it just opens the last used Settings detail window.

gnome-control-center --list shows several differences. info-overview got replaced by system subpanel about.
