fix(sharing): migrate QuickShareSelect to NcActions

[ShGKme]

• ⚠️ Requires @nextcloud/[email protected]
• Resolves: https://github.com/nextcloud/server/issues/43139

Summary

The current custom quick share select implementation has a number of a11y issues:

• The toggle button
  • is not focusable
  • has no button role
  • has no aria-expanded="false"
• The menu has popup role, better to have menu or select semantics
• Selected button is marked by aria-selected only on true, which is not allowed here and should has false value
• Keyboard navigation works, but the best is if Tab moves to the next UI element instead of the next option in the list

Having all of that, it seems that moving to NcActions with menu + menuitemradio semantics and some custom styles for the trigger is the best and easiest way to fix all a11y issues.
