The package's TypeScript types should be moved to DefinitelyTyped or it should be ported to TypeScript

This is pretty much the same as reduxjs/redux#3500, so please read that for my explanation and the pending discussion.

Ultimately the decision depends on how comfortable the maintainers are with TypeScript and if they want to support it directly (is so port, if not use DefinitelyTyped and remove the types from this package).

react-testing-library moved their typings to DT, but added them as a dependency to their package. Could be an interesting move for redux-devtools-extension too if you want to keep them in JS.

In my opinion, it's better to break back compatibility and allow more freedom in versioning the peer dependency.
