TODO: Update documentation of mfa module

[sabina-talipova]

Description

Revise the MFA module documentation to include details on the functionality of Method interfaces.

[phptek]

Additional effort required is not to bake-in the version of core in the admin-linked docs. Using https://userhelp.silverstripe.org/en/optional_features/multi-factor_authentication/ instead, should always take users to the latest docs version. Either that, or there's some kind of version detection logic to be added, which determines which version to link to.

Can I also suggest updating the QR code and manual code in the second screenshot on this page to be partially obscured, otherwise you get the occasional low-tech user who will scan that code and get an MFA entry in their app called "Your site name: garion@silverstripe.com" and they'll try enter codes from that entry which will fail

The codes mentioned in #513 (comment) have been anonymised in #612.

I'm keeping this issue open because presumably that wasn't the only bit of updating that should be done.
