(PA-6885) Add DigiCert Global Root CA G2 for puppetlabs.net

rubygems commands started failing on Windows due to a recent infrastructure
change, because ruby does not integrate with the Windows trust store. Add the
DigiCert cert as we've done in the past.

    $ openssl x509 -in resources/files/rubygems/DigiCertGlobalRootG2.pem -fingerprint -sha256 -noout
