Subject: [PATCH] hermes-engine should build with target Java version 17
 (#51162)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51162

We specify the java target version to 17 for ReactAndroid but not for hermes-engine.
This is causing it to be the default (8) which will cause our build to fail on JDK 21.
This fixes it.
