We are migrating towards using RTK Query for API calls, and using `msw` to mock APIs in our tests. RTK Query's `fetchBaseQuery` requires the use of `fetch` and `Request`. `fetch()` was added to Node in v18, and the ability to use it in Jest tests was added to Jest in v28. However, it still cannot be used with a `jsdom` test environment. Therefore, it is necessary to add a polyfill. There are several libraries available for this but many others in this situation have had success using `whatwg-fetch` and so it was selected somewhat arbitrarily. It is also important that `whatwg-fetch` is imported before `fetchBaseQuery` (otherwise, a nuisance console warning will be issued). To ensure this happens, it is imported in a Jest setup file.
