thanks @adityyyy, please update the myst markdown file instead of the notebook: https://github.com/unionai-oss/unionml/blob/main/docs/tutorials/quickdraw.md

Then the pre-commit hook here should render the notebook automatically (the .ipynb files shouldn't actually be edited)

closing this PR because edits don't contribute much to clarity of the writing
