Add prefer-node-protocol ESLint rule (#21532)

* Add `unicorn/prefer-node-protocol`

* Fix `unicorn/prefer-node-protocol` ESLint errors

* Run `npm run format:fix`

* Add sandboxed-module sourceTransformers in mocha setups

Fix `no such file or directory, open 'node:fs'` in `sandboxed-module`

* Remove `node:` in the SandboxedModule requires

* Fix new linting errors with `node:`
