Implement broken docs link check for `help_page_url` links
Summary
Rails.application.routes.url_helpers.help_page_url
is used to produce documentation links.
It would be great if we could have a CI check that detects when these links are broken.
Some things to consider:
- Documentation is aggregated from multiple repositories and may not necessarily be located in
gitlab-org/gitlab
.- This means that the job needs to be allowed to fail to avoid master:broken issues, as changes to the docs can be introduced outside the merge request workflow.
