fix(modify): bug in modify for graphql

[MedHeikelBouzayene]

Summary:
Resolved an issue where the @modify directive was not functioning correctly with the field's @graphql directive. The query sent by Tailcall to the original GraphQL server was incorrect.

Build & Testing:

• I ran cargo test successfully.
• I have run ./lint.sh --mode=fix to fix all linting issues raised by ./lint.sh --mode=check.

Checklist:

• I have performed a self-review of my code.
• PR follows the naming convention of <type>(<optional scope>): <title>
