Changed "commented" link in member feed to redirect to post

fix https://linear.app/tryghost/issue/ENG-1217/activity-log-link-for-comments-goes-to-wrong-place

- the post analytics page does not contain any comments, so it's not the
  most intuitive location to point the user. Instead, we can send them
  to the frontend of the post, where they can view comments
