(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
    SHA256 Fingerprint=CB:3C:CB:B7:60:31:E5:E0:13:8F:8D:D3:9A:23:F9:DE:47:FF:C3:5E:43:C1:14:4C:EA:27:D4:6A:5A:B1:CB:5F
