[BUG] useScrollLock doesn't work in ios safari

[jontewks]

Describe the bug

In ios safari, using this hook with the default of document body doesn't actually prevent scrolling.

To Reproduce

Open the menu on your documentation site on an iPhone and see that when you scroll to the bottom, you can still scroll the body behind the menu.

Expected behavior

You should not be able to scroll the menu.

Additional context

This works if you set overflow: hidden; on ios rather than overflow-y. Unless there was a specific reason for that choice to only do Y when moving from useLockedBody, reverting to preventing all overflow seems to do the trick.

Opened a PR and tested using the menu open on ios safari in dev mode and confirmed the body was locked correctly in ios safari.
