fix(useTable): work around React 18 useReducer eager bailout change (#4207)

React 18 removed some logic from `useReducer()` where a dispatch would eagerly call reducers to recompute the state so now reducers will be called after render. This poses a problem for `useTable()` because during render it mutates the `instance` by spreading in `props` and does not expect this to happen before reducer execution. We were passing a `pageCount: undefined` prop to `useTable()` and by the time the reducer executes `instance.pageCount` is been overwritten, causing a bug in our app. In the Codesandbox reproduction you can see that hitting the "next" button will not work. I understand that our abstraction around `useTable()` probably shouldn't be passing this prop when `undefined` but the behavior change was unexpected and I wonder if it breaks any other assumptions that this library makes. The fix I made here is to just replace `useReducer` with `useState`, which still has the eager bailout check.
