Bump Gradle to 9.4.1

- part 1 of Java 26 AGP 9 Kotlin 2.3-4 NDK 28 support
- bump root gradlew
- bump RNGP gradlew
- bump private\helloworld\android gradlew
  - locally fix missing private\helloworld\node_modules\react-native\sdks\hermes-engine\version.properties
- NB: call gradlew twice
  - once for config (gradle-wrapper.properties)
  - twice for binaries (gradlew, gradle-wrapper.jar)
- NB: gradlew.bat bins remain identical to 9.3.1
