Add pre-commit hook for Jupyter notebooks to reduce noisy diffs

[omkar-334]

While refactoring super() calls in notebooks, the notebook metadata kept changing, which led to a very big diff.
To reduce this in the future, we can add pre-commit hooks for this.

Possible hooks -
https://github.com/kynan/nbstripout - strips output

  # notebook JSON hygiene
  - repo: https://github.com/kynan/nbstripout
    rev: 0.7.1
    hooks:
      - id: nbstripout

https://github.com/nbQA-dev/nbQA - lints and fixes notebook cell code

  # notebook code quality
  - repo: https://github.com/nbQA-dev/nbQA
    rev: 1.8.7
    hooks:
      - id: nbqa-ruff
        args: ["--fix"]

https://github.com/srstevenson/nb-clean - removes metadata, outputs and execution counts

repos:
  - repo: https://github.com/srstevenson/nb-clean
    rev: 4.0.1
    hooks:
      - id: nb-clean

Hi @omkar-334,

I’ve opened PR #3585 to address this by adding the nbstripout pre-commit hook to automatically strip notebook outputs and reduce noisy diffs.

I chose nbstripout as a lightweight first step focused specifically on cleaning outputs and metadata. We can consider adding nbQA or nb-clean later if broader notebook linting or hygiene is desired.

Please let me know if you’d prefer a different approach or additional hooks included.

Thanks for raising this improvement suggestion!
