fix: remove aria-selected on elements with role link

[DilinaCP]

Motivation

Currently, elements with role="link" were being assigned the aria-selected attribute, which is incorrect according to accessibility guidelines. aria-selected is meant for elements in a selectable group (like tabs or list items) and should not appear on standard links.

This PR removes the aria-selected attribute from elements with role="link" to improve accessibility compliance and prevent screen readers from announcing misleading information.

Fixes: #9418

Test Plan

1. Run all existing tests to ensure nothing breaks:

   yarn test

2. Verify snapshots for Link component no longer include aria-selected for role="link" elements.

3. Manually check that web links still navigate correctly and styling remains unaffected.

4. Lint and TypeScript checks:

   yarn lint
   yarn tsc --noEmit

All tests pass, lint is clean, and types are valid.

The E2E failure seems unrelated to my changes. Could a maintainer please re-run the CI to confirm? Thanks!

Thanks for the PR.

However, this doesn't seem to fix the linked issue. DrawerItem, TabBarItem, and BottomTabBarItem don't use Link, but PlatformPressable, and not Link.

The proper fix would be to conditionally set aria-selected on these based on whether href is undefined.

aria-selected={href ? undefined : isFocused}
