Couple of chapters as demo for Quarto learning

[AlfonsoRReyes]

Hi Wes, amazing book! Thank you for sharing. I have started to learn Quarto and your book if one of the few -or the only one- that uses Jupyter files for the creation of a book. I have cloned your repo for this book but I am unable to find any source code for the book construction. Is there a chance that you could share a couple of chapters where we could see how you run .ipynb notebooks in Quarto? We will appreciate it very much.
