Summary:
Before this change, during the "Start Packager" Xcode build step that runs the packager, `packager.sh` was using my system node version and not the one from `nvm` that is meant to be used with the project.
## Changelog
[iOS] [Fixed] - Use `NODE_BINARY` from `.xcode.env` when running packager from Xcode
Pull Request resolved: https://github.com/facebook/react-native/pull/34121
Test Plan: Perform a build using Xcode and confirm that the packager is using the correct version of node.
