Update Auto DevOps demo to make it work with latest codeclimate version
Auto DevOps demo application (https://gitlab.com/auto-devops-examples/minimal-ruby-app) relies on the fixme
CodeClimate engine to spot a code quality problem and allow to fix and show the improvement in the MR widget.
With CodeClimate 0.70.0 this engine is not automatically loaded, so the script is not working.
We should find a way to use a different story that works well, or force the fixme
engine to on in Auto DevOps template.
