Apollo GraphQL VSCode extension: Prevent GraphQL Validation

Hello dear GraphQL community.

I've just installed the Apollo GraphQL VSCode extension, and I was wondering if there was an easy way to prevent the extension from validating my GraphQL files.
I already have linting handled by [GraphQL Eslint library](https://github.com/B2o5T/graphql-eslint), and the extension provide some validations that are, either not needed, or duplicated from my Eslint config.

Thanks in advance, and for the great work for this ecosystem we all love ✨!

Review the Apollo GraphQL VSCode extension's validation behavior and how it interacts with the GraphQL ESLint library. Identify the extension entry point and any existing configuration or validation tests before defining the disable mechanism. Done means users can prevent the extension's validation without disabling their ESLint workflow.
