Fix loading NODE_BINARY inside Generate Legacy Components Interop (#37802)

Summary:
When trying to build an app using 0.72.0-RC.5 inside a project that uses `.xcode.env.local` the  `[CP-User] Generate Legacy Components Interop` Phase script fails to run due to a `Permission denied` error. That's because `.xcode.env.local` is not being loaded, resulting in `NODE_BINARY=" "` and then the `React-RCTAppDelegate` script tries to run `generate-legacy-interop-components.js` directly.

E.g

![image](https://github.com/facebook/react-native/assets/11707729/ce72d7d1-69ab-4477-a754-10cd52bb21a2)

In order to fix this we should run the `with-environment.sh` script instead of directly loading `.${PODS_ROOT}/../.xcode.env`

## Changelog:

[IOS] [FIXED] - Fix loading `NODE_BINARY` inside Generate Legacy Components Interop

Pull Request resolved: https://github.com/facebook/react-native/pull/37802

Test Plan: Make sure you don't have a `.xcode.env` file and run locally a project that uses React-RCTAppDelegate
