[x] Documentation update

What changes did you make? (Give an overview)

Ensured that no-restricted-globals, no-restricted-properties, and no-restricted-syntax all linked to each other in their documentation.

Is there anything you'd like reviewers to focus on?

I'm not sure no-restricted-syntax really fits with no-restricted-globals and no-restricted-properties, but there was already a link between no-restricted-properties and no-restricted-syntax. Should I instead remove no-restricted-syntax from the other two rules? no-restricted-syntax points to rules like no-debugger which it supersedes.

I think this is fine, personally.

Whoops, formatting got wonky. Above comment should be:

Thanks @gyandeeps and @kaicataldo. I'm going to merge this. If something needs to change, I can do so in a separate PR.
