What does this MR do?
proxy_cache off; directive to the example NGINX config for GitLab Pages
Are there points in the code the reviewer needs to double check?
Why was this MR needed?
proxy_cache_key leads to pages being cached across GitLab Pages hosts. We weren't expecting NGINX to do any caching, so disabling it is the best option.
