Add Additional Information for Redux-Persist

I was working on a project where I implemented RTK with redux-persist following the docs for RTK but I wanted to ‘flush’ storage on user logout which seems to be a fairly common action and it wasn’t immediately apparent how to accomplish this with RTK based on current documentation. Here was the final solution:

import { PURGE } from "redux-persist";

...
extraReducers: (builder) => {
    builder.addCase(PURGE, (state) => {
        customEntityAdapter.removeAll(state);
    });
}

Can I open a PR for this addition to the docs?

Always 😃

Well at least one thing is certain, RTK is an awesome product!

I would be more than happy to add it to the docs if you would like?
