* Change package json commands and turbo repo config to allow for greatly simplifying running turbo
* Remove require-turbo script which was causing caching issues
* Colorize CI output from scripts
* Add missing changelog script to extend-cart-checkout-block
This replaces all `nx` commands with `turbo` commands and removes Nx from the repository. All of the `project.json` files have been removed and any commands that broke with Turborepo have been adjusted.
