Internalize type definitions

[kentcdodds]

It would help with issues like #121 and in general I don't think there's a lot of value having them externalized to DefinitelyTyped (https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/testing-library__cypress). Let's bring them in.

Anyone wanna work on this?

I am happy to pick this up.

This one is in progress. I am encountering some issues with conflicting type definitions but it's getting there.

I haven't been able to figure this out and I am kind of stuck now :-/ I am quoting my message on Discord about the issue

So, the precommit hook complains when running tsc because some jest and cypress type definitions are conflicting. I've looked into other similar PRs in testing-library packages but I couldn't find a solution.

Is it worth opening a PR with what I have so far?

Yes, please skip the hook if it's preventing you from opening your PR.
