fix: version selector not 'hoverable' on some Android devices

[axieum]

It appeared that the pointer media query for my Pixel 7 Pro device was reporting as pointer: fine, meaning the hover fix wasn't applying to the Version selector.

I can see this is already being used here:

mkdocs-material/src/assets/stylesheets/main/_typeset.scss

Lines 295 to 296 in f458f04

	// Show tooltip for touch devices
	@media (hover: none) {

I confirmed working on Desktop, Android, and an iOS mobile device, but it may be best to triple check iOS compatibility please.

Developer Note: When you have Dev Tools connected to the Android device, it changes to pointer: coarse and works as expected, making debugging quite difficult. So you mustn't observe with Dev Tools open while trying to reproduce the error on an Android device.

Fixes #2429

Thanks for the PR! I'm not feeling confident to merge this through right now, because some touch devices will not match hover: none (need to check for more sources), at least as far as I know. IIRC, pointer: coarse is the recommendation and we probably should switch other parts of our code base to it, but I don't have an Android or Windows phone at my disposal, so we definitely need to test this thoroughly before merging with the help of other users.

Agreed. I did originally have @media (pointer: coarse), (hover: none) {, shall I bring that back?

If you're confident that it solves the problem, we can give it a try.
