Some of this links direct the user to the issues and merge
requests linked to the subgroup. Nevertheless, the url

Centralize markdownlint configuration

See merge request gitlab-org/gitlab-ce!30263

To ensure `mdl` is available it's also added to the `Gemfile`, though
CI will still use the version installed in the `gitlab-docs-lint` image.
