Continues the introduction in core of the aria-current attribute after [41683], [41359], and [41371]. - changes the `wp_link_pages()` (see the `nextpage` quicktag) output to use an `aria-current` attribute on the current item - adds `post-nav-links` and `post-page-numbers` CSS classes to help themes style these links - updates the related tests Props antonioeatgoat, alexstine. Fixes #41859. git-svn-id: https://develop.svn.wordpress.org/trunk@42440 602fd350-edb4-49c9-b593-d223f7449a82
