change Whonix Home to www and update proof

[adrelanos]

Whonix is currently listed as redirects. It's true it redirects from the apex domain name (no sub domain) to the www subdomain. But that should be alright, I guess.

By adding www (which is consistently used) it would fix the redirection notice in this list here.

https://www.whonix.org/wiki/Forcing_.onion_on_Project would be a better proof since on the project homepage. (Also using onion-location HTTP header.)
