fix(pagespeed): update fqdn + instructions

this fixes the deadlinks for pagespeed, see [https://github.com/apache/incubator-pagespeed-ngx/issues/1656](https://github.com/apache/incubator-pagespeed-ngx/issues/1656).

Also added clearer instructions if pagespeed is used as a module so that users know to adjust their `nginx.conf`

nginx-autoinstall.sh
