Add aria-current to output of Walker_Page

[chetan200891]

From the reference of ticket #43191, Also need to add area-current to output of Walker_Page.

I think below modifications can help.

if ( $page->ID == $current_page ) {
        $atts['aria-current'] = 'page';
}

Looks like this has a patch, so updating the keywords.

Discussed during today's accessibility bug scrub and we'd like to propose this ticket for 4.9.9 consideration.

Patch looks fine on my side.

This ticket is triaged in milestone 5.0.3. It will needs commit and backport to the related branch.

[desrosj]

Going to punt this to 5.1. It is outside of the scope for 5.0.3 (block
editor bugs, regressions, and major bugs).

Accessibility: Themes: use aria-current for the Walker_Page current link.

See [42808] for Walker_Nav_Menu.

The aria-current attribute is a simple, effective way to help assistive
technologies users orientate themselves within a list of items. Continues the
introduction in core of aria-current after [42440], [41683], [41359], and [41371].
