## For Contributors
### Improving Documentation
- [x] Run `pnpm prettier-fix` to fix formatting issues before opening the PR.
- [x] Read the Docs Contribution Guide to ensure your contribution follows the docs guidelines: https://nextjs.org/docs/community/contribution-guide
### What?
Add instructions for using `bun/bunx` where relevant. I only added mentions where npm/yarn/pnpm were all already listed.
### Why
Bun can be used as a runtime-agnostic [package manager](https://bun.sh/package-manager) and script runner in any project with a `package.json`.
(Sorry, I probably should have consolidated this with https://github.com/vercel/next.js/pull/53467)

Previously, this warning message assumed the user knew what `yarn` was and had it installed.
This PR changes the warning message to assume the user knows what `npm` is and has it installed, since `npm` ships with the official `node` installation.
