audrasjb c58a08d9df Menus: Hide the "Remove selected item" from Menus screen when no item is selected.
This changeset removes the "Remove selected item" from the classic Navigation Menus screen when no item is selected, and makes it non focusable from assistive technologies.

Plus, this changeset fixes a small unrelated coding standard issue in `nav-menus.css`.

Props kebbet, joedolson, audrasjb.
Fixes #56942.
