[Docs] Update Super ALT↯TAB to remove use of unregister_code16 (#5766)

The code as originally listed didn't work for me, but replacing `unregister_code16(LALT(KC_TAB));` with `unregister_code(KC_LALT);` fixes the problem and causes the macro to work as intended.

Thanks to folks on Discord for helping me figure this out.
