Subject: [PATCH] Editor: A11y: Set ARIA attributes for Classic Editor link
 inserter.

Set `aria-modal` and `aria-hidden` attributes when the Classic Editor link inserter modal is active, so that content behind the modal will be properly treated as inert when interacting with the modal.

Props lyonmuller, jwgoedert, sabernhardt, alexstine, afercia, rajinsharwar, rcreators, audrasjb, hmbashar, joedolson.
Fixes #60799.
