The navigation treeview example uses aria-current="page" to indicate the current item, which differs from the general treeview pattern's mention of aria-selected. This was causing confusion for users.
This change adds an explanatory note to the "Accessibility Features" section, clarifying that aria-current is used because it more effectively communicates the state of a navigation widget. The new text follows the project's editorial style guidelines.
Closes #3371
