Evaluate alternative GraphQL clients

[nathanielrindlaub]

We chose graphql-request originally because it was lightweight and flexible, but now that we've migrated to Apollo Server v4 a few new needs have come up that graphql-request doesn't fully support:

1. a clean way to handle network errors (see [Discussion] Better error handling graffle-js/graffle#5)
2. graphql-request does support aborting in-flight requests (Implement request cancellation #205), but it may be challenging to store AbortController instances in Redux state

Some alternatives to consider are:

• Apollo Client
• Redux Toolkit Query
