chore: refactor pub/sub iterator usage across schema files

- Updated pub/sub iterator methods from `asyncIterableIterator` to `asyncIterator` in multiple schema files for improved compatibility with the latest GraphQL subscriptions.
- Refactored subscription logic in CollaborationSession, Document, Message, User, and other schema files to enhance readability and maintainability.
- Adjusted imports in GraphQL builder to utilize RedisPubSub for better performance in subscription handling.
