I'm working on examples/with-graphql-react changes to:
- Next v7 to v8.0 and update dependencies
- fix some errors for the change of graphql-react API

Adds an example with [`graphql-react`](https://github.com/jaydenseric/graphql-react), using [`next-graphql-react`](https://github.com/jaydenseric/next-graphql-react).

[`graphql-react`](https://github.com/jaydenseric/graphql-react) is a lightweight but powerful [GraphQL](https://graphql.org) client for React; the first [Relay](https://facebook.github.io/relay) and [Apollo](https://apollographql.com/docs/react) alternative with server side rendering.
