Improve Runner Settings Helper Text
Problem to solve
As described here: gitlab-design#664 (closed)
In the existing GitLab experience, it's not clear what's the goal of the Runners in the context of the CI/CD settings. Users who find this setting have to dig deeper and likely Google the GitLab docs to get the full context of the features and role of the Runner. In comparison, other available settings in the CI/CD settings, like Variables, provide more literature and informational artifacts to contextualize the users about that feature.
Intended users

Further details
Proposal
To solve this issue we should improve Runner settings helper texts to increase the context of the feature. As part of this issue, we should also add a link within the context of the helper text to point users to the documentation.
