♿️(frontend) change aria-label for help menu button

The help menu button's aria-label was
previously "Open onboarding menu", which was not
accurate and could be confusing for screen reader
users. This commit updates the aria-label to
"Open help menu" to better reflect the button's
purpose and improve accessibility.
