Ruby gem vulnerability CVE-2019-13117

Fixes: vmware-tanzu#2092
Resolves: CVE-2019-13117

Updated gemfile.lock for security vulnerability.

Updated Gemfile to specify gem versions, providing more control over versions when using bundle update. Including the Jekyll version in the Gemfile tells Nelify which version to build with.
