fix(keybinding): register both Super_L and Super_R when adding Super key shortcut

When a user registers a shortcut with either Super_L or Super_R key,
the system now automatically registers both keys together. This prevents
the issue where a user registers a shortcut with Super_L but pressing
Super_R on the keyboard does not trigger the shortcut, and vice versa.
