Migrate from express-graphql to graphql-http

Hello.
I'm getting this warning on `npm i`
```
npm WARN deprecated express-graphql@0.12.0: This package is no longer maintained. We recommend using `graphql-http` instead. Please consult the migration document https://github.com/graphql/graphql-http#migrating-express-grpahql.
```
Is it nessecary/possible to update this dependency?
Thank you.
