[Documentation] Generate an exhaustive list of configuration items

[jobimrobinsantos-drizly]

Hey y'all!

I'm working to implement an organizer.yaml on my organization, and it would be extremely helpful if there were a page listing every valid element that could possibly be in that file (even if some are mutually-exclusive). I'm having trouble making sense of the different examples that exist today and are slightly different from one another:

• https://github.com/gitconsensus/GithubOrganizer/blob/master/example.yaml
• https://organizer.gitconsensus.com/#/?id=examples
  See, for example, the use of required_pull_request_reviews versus required_status_checks.

The GitHub API documentation sort of gives me an idea of what Organizer can do, but it looks like not everything that the API can do is implemented in Organizer, so I'm looking back and forth a bunch 😕
