feat: GraphQL Queries

[jptissot]

This adds the ability to create Queries that use the GraphQL syntax

Todo:

• Add GraphQL Syntax to Codemirror (edit: I tried and could not get it to work. Will refactor this later)
• Documentation
• Cypress test
  • Recipe that create the query and a liquid page that displays the results

Make a PR to OC with these changes, I think this could be integrated in the core.
