Follows #53115 - Replace `chalk` with `picocolors` - Note that `chalk.hex('#007acc')` has been replaced with `picocolors.blue` - Replace `glob` with `fast-glob@2.2.7` - Not only does `fast-glob` is a faster drop-in replacement of `glob` with first-party `Promise`-based API support, but also `fast-glob` is already a dependency of `cpy`: <img width="812" alt="image" src="https://github.com/vercel/next.js/assets/40715044/8efa24c4-5312-4b1c-bf8d-68255ca30b60"> Together the PR removes about `50 KiB` from the `create-next-app/dist/index.js`: <img width="570" alt="image" src="https://github.com/vercel/next.js/assets/40715044/db2f3723-14cc-48ce-9cb2-8aa1fb1d5e95"> Co-authored-by: Steven <229881+styfle@users.noreply.github.com>
