Use prettier for GraphQL query prettification

[chasingmaxwell]

This PR uses prettier to format GraphQL queries which addresses #2023.

There were some diffs in a couple package-lock.json files that seem to be related to my environment. Particularly the removal of "dev": true all over the place. I did some looking up on how to resolve this, but was having little luck. If this is undesirable, do you have any suggestions for what I can change locally to avoid it? I'm using nvm to manage the node version according to the .nvmrc file. Maybe npm version?

While I agree that having prettier be part of the app would be awesome, it's a huge dependency to be adding just to format a GraphQL query. Do you think there's a way to do this with the current graphql library?

I'll look into it a bit more. If not, I'm happy to go the plugin route.

There is not a way to do this currently with the graphql library. There is an issue to add pretty-printing and some related pull requests, but for now print is the only option and its primary function is not for prettifying. It looks like the recommended approach for now is to use prettier so a plugin is the way to go here.
