Apply code formatting for accessibility to Jupyter notebooks (and Quarto code cells?)

[mfisher87]

Code formatting can significantly improve the accessibility of code in addition to enforcing consistency. Reviewing a how-to today on the mentor call I noticed some Python code that I felt could be formatted more accessibly. The Black project is a Python code formatter that puts readability first.

We can use the black-jupyter code formatter, or maybe something else, to do this using CI. I think the formatting can be very accessible using pre-commit.ci, so formatting can be done automatically by posting a comment containing the magic words "pre-commit.ci autofix" to any PR. We can use PR templates to instruct PR authors of this as well.

There's a Quarto extension too, but not sure about how to make the user experience good: https://github.com/shafayetShafee/black-formatter

Thoughts?
