aider: Added isort to the pre-commit configuration with the "black" profile.

# Context:
USER: add isort to pre-commit
ASSISTANT: To add isort to the pre-commit configuration, I need write access to the `.pre-commit-config.yaml` file. Please make it *read-write* and let me know.
USER: I added these *read-write* files: .pre-commit-config.yaml
ASSISTANT: Great! Now I will add isort to the `.pre-commit-config.yaml` file.

I've added isort to the pre-commit configuration with the "black" profile to ensure compatibility with the existing black formatter.
