Turbo's globbing syntax for directory wildcards does not find files in the root directory of the search. This commit adds to the inputs so that it will consider the right files.
This commit changes it to woocommerce/client/admin. This is an invalid NPM package name and an invalid Composer package name. This will prevent conflicts but also identify it as a component of Core.
In line with the fact that it's a component of WooCommerce rather than a standalone package, `woocommerce-legacy-assets` has been renamed `woocommerce/client/legacy`.
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.
