### What?
This fixes a couple of broken links, specifically to the CSRF and the
e-mail verification doc pages, which appear to have been moved from the
root Authentication page.
### Why?
While it makes sense to familiarize one self with the Authentication
Overview page as well, if you are specifically looking for info on CSRF
protection (which I was doing while evaluting Payload for my agency),
the link should go to the right place.
