Task: Split up into template and setup CLI 🪓

[nx10]

Description

There is a few awkward tradeoffs in this repo because it is supposed to be the template itself while also containing bootstrapping procedures and documentation for the setup process and itself.

E.g.:

• Release action that releases the template would look different than one that releases a package (e.g. setup and dev docs would need to be included)
• Zenodo badge referring to the template vs template zenodo badge for use downstream
• Dependencies might not be the same between setup and template

Tasks

• Move setup related things to a separate CLI package that lets you do something like cmi-template init myproject
