Fix pod install for swift libs using new arch (#38121)

Summary:
This fixes a bug that started with React Native 0.72.0 when using the new architecture and installing a native lib that has Swift code (in my case, `datadog/mobile-react-native`).

Running `pod install` errors with the following output (`DatadogSDKReactNative` is the pod containing the Swift code):

```
[...]
Analyzing dependencies
Downloading dependencies
Installing DatadogSDKReactNative 1.8.0-rc0
[!] The following Swift pods cannot yet be integrated as static libraries:

The Swift pod `DatadogSDKReactNative` depends upon `React-Fabric`, `React-graphics`, `React-utils`, and `React-debug`, which do not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set `use_modular_headers!` globally in your Podfile, or specify `:modular_headers => true` for particular dependencies.
```

Indeed, this pods were added as dependencies in `packages/react-native/scripts/cocoapods/new_architecture.rb` but do not define modules contrary to the other pods in the list.

This PR is solving a problem that already occured in the past and was solved here: #33743
It's a new implementation for the PR initially opened here: #38039

## Changelog:
[IOS] [FIXED] - Fix pod install for libraries using Swift code when the new architecture is enabled

Pull Request resolved: #38121

Test Plan:
1. Clone [this](https://github.com/louiszawadzki/react-native) repo
2. From `main`, add a Swift file to the `MyNativeView` native module in the RN tester app (see inspiration from [this commit](fortmarek@26958fc))
3. Try to run `RCT_NEW_ARCH_ENABLED=1 USE_HERMES=0 bundle exec pod install` inside the `packages/rn-tester`
4. Observe errors
5. Apply [the commit](7b7c3ff) from this PR
6. Both pod install and the subsequent build should succeed.
7. Revert the changes and repeat steps 2 to 6 with `RCT_NEW_ARCH_ENABLED=1 USE_HERMES=1 bundle exec pod install`
