Add an example with graphql-react

[jaydenseric]

Adds an example with graphql-react, using next-graphql-react.

graphql-react is a lightweight but powerful GraphQL client for React; the first Relay and Apollo alternative with server side rendering.

This should probably use latest like the other examples.

At the time I surveyed the examples and noticed about 17 don't use latest for the next dependency. This is a good thing, since examples are not guaranteed to work when (not if) breaking changes to next are published in a major version.

There are almost no valid use cases for * or latest. Inexperienced people that download and run examples locally are likely to use them as a boilerplate for their own projects, and they will not know that latest is risky anti-pattern that will eventually blow up their project.

When the next major version of next is published I will be sure to publish a new version of next-graphql-react that supports it, with an updated peer-dependency range, and update the dependency in the example here.

Seeing the major version of next supported by each example in package.json is also useful, as when a major new version is published not every example is guaranteed to work on day 1. It lets you know how up to date the example and the third-party projects are.

I've pulled in the latest from canary branch and fixed a Standard Style lint issue, so CI is passing now. Should be good to merge?

Thanks!
