chore(toe): update graphql-toe and add instructions to README

[benjie]

Summary

Hi, I'm the maintainer of graphql-toe and we just put out a new release, v1.0.0-rc.0, which fixes an issue where errored arrays would be replaced with a null prototype object with array indicies but not an instance of array. We've also overhauled the README with greater detail.

Set of changes

This PR:

• upgrades to this new release of graphql-toe
• moves wonka from dependencies to devDependencies
• adds extra detail to the README

Please check the instructions I placed in the README, I'm not familiar with the exchanges system (I don't really do frontend work these days, mostly just backend stuff!) so am not certain I put the exchange in the correct position in the array. The tests didn't help clue me in since they don't seem to follow this pattern.

cc @JoviDeCroock who I have been DM-ing about this :)

Though this is a major release of graphql-toe, it's only a patch release for this exchange - it fixes a bug and adds some documentation. Changeset added and other issues addressed 👍
