Chore: Update the source of json_refs gem (#565) (#566)

At the time of using, `json_refs` gem did not have the ability to recursively resolve the references. So we had to fork this into one of our own and make the required changes. So this fork was used as the source for the gem.
Along with this, we had raised a PR in the original repo so as to push the recursive dereferencing changes upstream. This was merged in the gem's parent repo. So updated the source of this gem to the original parent repo source.
