Update noxfile.py

[dustinmichels]

Hallo! 👋 I am a huge fan of your tutorial, thank you for putting it together!

To get nox working, I had to include the argument --without-hashes along with the poetry export command. Otherwise I get errors. For example, running:

nox -s black

I get the error:

ERROR: In --require-hashes mode, all requirements must have their versions pinned with ==. These do not:
    black from https://files.pythonhosted.org/packages/d2/16/a92c999103bee1236dd93f703f3522217fe00bd97bd50ae3699c2d91e320/black-21.9b0-py3-none-any.whl#sha256=380f1b5da05e5a1429225676655dddb96f5ae8c75bdf91e53d798871b902a115

I am a bit confused by the error, but if it seems reproducible maybe you'd like to include this change?

My setup:

Poetry==1.1.10
nox==2021.10.1
Python==3.9.7

Thanks again!
