chore: update codemirror-graphql & react

[acao]

We have made many improvements to codemirror-graphql and the underlying language services since this version, including interface implements interface, variables completion, and more

I also upgraded electron so that yarn install would work on my M1

We will take care of possibly publishing an electron version later.

I can't reproduce this tslint issue locally, so I guess I can't publish :(
