[FEATURE_REQUEST] Illustrate CI usage in documentation

[TobiasCGoetz]

Description of the problem/feature request
Currently there's not much guidance in setting up KubeLinter as part of a CI pipeline. While there's a Red Hat article about it, I'd prefer if the information was easier to find.

Additional context
I intend to create a PR adding basic documentation for a CI use case. If anyone beats me to it - all the better.
