* Rewrite "Set up development environment"
The previous version is specific to Python as it uses
`buildPythonApplication` instead of `mkShell`.
This one is more general but maintains the same Python Flask web
application example.
* Update pinning-nixpkgs to use 22.11

There are a number of code samples throughout nix.dev. How do we know
they still work? We don't!
This commit introduces a way for us to extract these code samples into files
and then run tests against them in CI. This will hopefully help us catch
regressions in future updates to nix, NixOS and/or this guide.
Additionally, I included a darwin specific nix-shell configuration that I
use personally on my M1 Mac to work on this repo. Might be useful for someone.
