Linting fails with @graphql-eslint/no-unused-variables when variable used in a fragment

[beaucollins]

Describe the bug

A query operation in one graphql SomeQuery.graphql defines a variable to be used by a fragment in another document SomeFragment.graphql fails linting and is told the variable is unused even though it is used by the fragment.

To Reproduce
Steps to reproduce the behavior:

• Checkout @beaucollins/graphql-lint-fragment-variables
• npm install; npm run lint;

Example of failure: beaucollins/graphql-lint-fragment-variables@91fee89#annotation_1981886819

Expected behavior

This should not be an error because the variable is used according to @graphql-eslint/no-unused-variables:

A GraphQL operation is only valid if all variables defined by an operation are used, either directly or within a spread fragment.

Environment:

• OS: macOS 11.5.2
• @graphql-eslint/eslint-plugin@2.2.0
• NodeJS: v16.9.1

Worth noting there is no failure when the fragment is embedded: beaucollins/graphql-lint-fragment-variables@0c0cab2
