To Reproduce Steps to reproduce the behavior:

my configuration file like:

      "schemaPath": [
        "packages/data-api/schema/universe.schema.graphql",
        "packages/data-api/schema/platform.schema.graphql"
      ],
      "includes": [
        "packages/front-lib/src/**/*.{ts,tsx,js,jsx}",
        "packages/front-lib/schema/*.graphql"
      ],

When lint packages/front-lib/schema/schema.grapql, the error will be reported. But I have another project config, like:

 "schemaPath": [
        "packages/data-api/schema/universe.schema.graphql"
      ],
      "includes": [
        "packages/data-api/src/**/*.{ts,tsx,js,jsx}",
        "packages/data-api/schema/*.graphql"
      ],

when I edit and save all graphql file in packages/data-api/schema/ directory, there is no error reported. This is weird.

Expected behavior

Treat this file as graphql and lint it.

Environment:

• OS: Ubuntu 20.04
• @graphql-eslint/eslint-plugin: 3.20.1
• Node.js: 20

Additional context

[charleslai2000]

I found some hint, can not include *.graphql in graphql-config's includes entry. But this is not consistency with document provided by graphql-config.
