Recent updates seemed to stop rake task themes:update to use a proxy server

Recent commits in GitHub seems to stop theme components updater to use a proxy server. I remember that they can be updated through a proxy server (set in env vars HTTP_PROXY and HTTPS_PROXY) in the past, but now they do not.

Add NO_PROXY='127.0.0.1, localhost, <internal-network>, github.com'
