Is the graphql schema file populated somewhere?

@kevinmamaqi you can use wp-cli to generate a schema file.

The command is wp graphql generate-static-schema

You can see it in action in our Github workflows: https://github.com/wp-graphql/wp-graphql/blob/3735d056d4d8a00bafb0f0002bb7e611989aff39/.github/workflows/schema-linter.yml#L52

This results in the schema.graphql files being uploaded as artifacts on the releases: https://github.com/wp-graphql/wp-graphql/releases
