Add eslint-plugin-react-hooks

[jgierer12]

It would be cool to add eslint-plugin-react-hooks, which is the official plugin by the React team to enforce the 'rules of Hooks'. Seeing as it will be added to Create React App soon, I would like to see it in Healthier too.

This shouldn't be a breaking change, since it only applies to projects using Hooks anyways and is a relatively unopiniated enforcement of the rules that are present in the React docs too.

If you approve of this change, I will work on a PR for it.

Yes! In general, this sounds like a good idea.

We had a little bit of discussion regarding how to best handle React stuff in healthier in general. Some here KidkArolis/healthier#20 and here KidkArolis/healthier#16.

I need to reread those myself, but I just want to ensure that healthier, just like standard, doesn't break in non React environments. E.g. if someone's using jsx with Preact or any other library, you shouldn't get issues flagged that are only relevant for React.

So one thing we talked about was detecting if you have react installed.

Actually, in the meantime, we can just keep this in healthier/react config. Maybe that's what you had in mind? So yes, let's definitely add plugin-react-hooks into healthier/react.

Yes, that is exactly what I had in mind 👍

I will add it and open a PR shortly.
