Typescript Error when using states created via combineReducers with Redux >v4.0

[brwarner]

A recent change to Redux's type definitions has made the CombinedState<S> type imcompatible with Record<string, unknown>. This causes a type error when trying to pass such a state into any of this library's methods. (for an explanation on why, see: microsoft/TypeScript#46715)

A temporary solution is to keep using Redux v4.0.0. If you're using a newer version of redux/toolkit, you can add a resolutions block to your package.json like so:

"resolutions": {
    "redux": "4.0.0"
}

I have yet to encounter any issues user newer versions of toolkit with v4.0.0 of redux, but an real solution should be found to update this library.
