Fix caddy forward_auth settings for authentik

The snippet will now set the correct Host for the next hop and keep the
original site in the X-Forward-Auth-Host. The authentik caddy-site will
then put the X-Forward-Auth-Host into the X-Forwarded-Host (which would
normally be the authentik host/domain). Authentik is able to handle the
X-Forwarded-Host header.
