Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/39566 Fixes running the `build.sh` script for `react-native-codegen` when on [EdenFS](https://github.com/facebook/sapling). This would previously fail due a filesystem "unable to copy extended attributes" error. This only affects development within the React Native monorepo. Practically, this equates to a workflow improvement for Meta engineers when creating `RNTester` builds. NOTE: **This is temporary**. The change from `mv` to `cp -R` makes this script more expensive, which will make Android builds via Gradle take slightly longer. I have a WIP cleanup planned which will 1/ move `react-native-codegen` to the [shared monorepo build setup](https://github.com/facebook/react-native/pull/38718), and 2/ drop this step entirely from the Android Gradle build.
