Explore hatch vs. nox for managing high level developer workflows

Need to decide if we can use hatch envs with the current workflows that we have around nox (which I don't want to change in this PR) or if we'll need to remove hatch envs for the time being and make an Issue to decide how to move forward using nox and hatch in the future.

Let me know if you have any questions! Environment management and configuration is probably the feature I put the most thought and design work into so I'm interested to see how this goes 🙂

Based on https://github.com/scikit-hep/pyhf/pull/2118#issuecomment-1432584212 @kratsg and @agoose77 do you have any clever thoughts on how to determine if tensorflow or tensorflow-macos should be installed at runtime depending on if the user is on an Apple silicon Mac or not while using hatch environments?

Do environment markers not work for this use case?

Yes, yes they will. Thanks @ofek! (I actually do generally read the docs for projects, but I also usually post these GitHub comments as reminders to do so when it isn't after midnight local time for me).

The way that hatchling does this is actually super nice, so many thanks for all the work that went into this design. :+1:
