Make 'retry' consistent in Composer and CMS jobs
The `retry:` value in the Composer jobs works as intended. But there is no `retry:` in the Drupal CMS job, and a failure results in no attempt to re-run. We do have a [default section in the template](https://git.drupalcode.org/project/gitlab_templates/-/blob/main/includes/include.drupalci.main.yml#L544-555) but the retry setting here is not used in the Drupal CMS job. It would be good to know how that 'default' definition is used, and why it does not apply to the CMS job.
