Pull Request resolved: https://github.com/facebook/react-native/pull/33672
This pr adds a parameter to the `create-artifacts.js` script to accept the path to a node executable, falling back to `node` in case the parameter has not been passed.
Then, it passes the NODE_BINARY to the script in the `script_phases.sh` script.
This PR decouples the `node` environment from the system one and fixes a build issue in the new architecture when the environment has no `node`
## Changelog
