Allow to set active and disabled class also to .page-link (#35804)

Allow to set active and disabled class also to .page-link (#35804)

Sometimes we can set `.active` class only to link tag and not parent.
Since active status style is applied only to `.page-link` and not `.page-item`, would also make more sense to just add the active class to `.page-link` itself.

The other way to set `.active` class to `.page-item` still remain, so there is not BC.

Allow to set also `.disabled` class to `.page-link`
