Accessibility: List Tables: use aria-current for the views current link.

Browse Source 
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 the `aria-current` attribute after [41359] and [41371].

Props joedolson, flixos90, afercia.
Fixes #32399.
