Use blacken for docs

🚀 The feature

Hi! I just wanted to ask if you could add blacken to your pre-commit! It’s an amazing formatting library for markdown code blocks. It would make the docs so much easier to read.

Motivation, pitch

I find it quite frustrating having to scroll horizontally back and forth to read a simple line of code on my laptop, and it’s literally 5 min to implement.

I also wanted to thank you for this amazing project!
