Render the result of the corresponding job in case of failure in the Security Widget
In https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/5340, we are displaying a warning on the pipeline, but not in the Security scanning group. This can be confusing for the user and could lead to think everything went well, and there's no security issue.
We should display at least a warning in this section: to indicate that the dependency scanning job failed.
