Lock codeclimate to version 0.69.0 in Auto DevOps template

With Code Climate 0.70.0 there is no init command, but also predefined engines are changed and we cannot get fixme warnings by default.

This will break script for Auto DevOps demo app.

The quick fix is to lock version to 0.69.0, so it will work as expected, and then change the demo app (https://gitlab.com/gitlab-org/gitlab-ce/issues/40376).
