should explicitly declare type:commonjs since Node experimental-detect-module is on by default

Description

With recent Node versions a vitest test suite which tries to load react-native will load it as a module rather than as commonjs, and that will lead to SyntaxError: Unexpected token 'typeof'

This happens for all Node versions that have experimental-detect-module set to true by default, that is Node 20.19 and later, Node 22.7 and later, Node 23 (all versions) etc.

What I think happens is that based on the index.js file, node detects that React-Native is ESM and tries to run it as a module.

One workaround is to configure this script (see npm run dev below)

"dev": "NODE_OPTIONS='--no-experimental-detect-module' vitest"

Steps to reproduce

1. checkout the reproduction repo, run npm install
2. switch to a recent node version like 20.19 or later, 22.7 or later, 23
3. npm run test (which executes vitest) will fail with SyntaxError: Unexpected token 'typeof'. npm run dev (which also executes vitest, but with the flag above) works for all node versions >= 20 (earlier node versions do not recognize the flag). npm run expo works for any Node version supported by React Native.
4. edit node_modules/react-native/package.json and add "type":"commonjs". This will help npm run test work as expected.

Tested on a number of macOS and linux platforms, the behavior is the same. The difference is made by the Node version

vitest tests break with SyntaxError: Unexpected token 'typeof'

Screenshots and Videos

Commencez par les métadonnées du paquet React Native et le comportement de index.js décrits dans l’issue, puis exécutez le reproducteur lié avec npm install et npm run test sur une version de Node affectée. Comparez ce résultat avec npm run dev et avec la modification de package.json décrite ; c’est terminé lorsque la suite de tests n’échoue plus sans le contournement NODE_OPTIONS.
