Title: Switching to secure rubygems.org source

When running bundle on the client-gem Gemfile, a deprecation warning was
being shown.

The source :rubygems is deprecated because HTTP requests are insecure.
Please change your source to 'https://rubygems.org' if possible, or
'http://rubygems.org' if not.

Switching the source line fixes that warning.
