Fixes #27503 (closed)

Why was this MR needed?

Features section in /admin page doesn't expose status of a particular feature to screen-readers, this MR fixes it by adding aria-label attribute to feature element that include feature name as well as status of feature (being on or off).

It also adds missing aria-label for Project > Settings > Integration service status.
