refactor: update outdated tooltip on menu setting (#7330)

Followup from https://github.com/Comfy-Org/ComfyUI_frontend/pull/4312:
remove tooltip with outdated info discussing the bottom menu. The bottom
menu setting is removed and even if it was not removed, the logic that
forced the menu to the top on mobile was removed, so this tooltip is
outdated and gives wrong info.
