Major update

[koddsson]

Removing a ton of stuff I don't think we need any more as well as trying to simplify the whole repo, hoping to eventually get down to a list of rules and their documentation.

I'm down to reverting any of these changes if you think we should still keep it.

This is a first pass and I want to do more after this is merged.

As far as I can tell, this isn't used for anything.

One thing we could do is create a new eslint-config-github repo and keep the current repo as is. That would mean that this repo can just be deprecated and archived.

Apparently you need to name the package plugin in order for you to define your own rules. With that in mind I might just break this PR into smaller PRs and keep it in the same repo. I'll bump the major version once I got all those PRs out and maaayyybe rename the package to something like @github/eslint-plugin.

There's more stuff to do for 4.0.0. I'll open up a tracking issue for those outstanding issues.
