└── react-native-macos@0.81.0

node -v: `v20.20.0`
npm -v: `10.8.2`
yarn --version: Not installed
xcodebuild -version: 

Xcode 26.0.1
Build version 17A400

Steps to reproduce the bug

1. Run npx @react-native-community/cli init ProjectName --version 0.81
2. Run npx react-native-macos-init
3. cd macos && bundle install && bundle exec pod install

Expected Behavior

pod install should succeed

Actual Behavior

Additional context

This is probably because of the new config structure for codegenConfig in package.json - https://github.com/microsoft/react-native-macos/blob/main/packages/react-native/package.json#L200C3-L231C4

If i change the structure back to how it was in previous versions in both react-native's package.json and react-native-macos's package.json, it works as normal
