* 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.
Thanks to our build orchestration tooling, there is
no reason for us to build all of the packages on
`install`. In cases where `prepare` was used to
build before packaging, this changes it to
`prepack` so it will run only under the correct
circumstances.
