update targetSdk to 35 (facebook#47738)

Summary:
Pull Request resolved: facebook#47738

- updating targetSdk to 35 for RN Android and helloworld
- **Note:** `tagetSdk` of RN Android does not have effect on the app's targetSdk. App can set `targetSdk` regardless of what RN targetSdk is. Updating the targetSdk just signals that RN Android has been tested with targetSdk 35 and apps can choose to support lower targetSdk as needed.

Changelog:
[Android][Changed] updating targetSdk to 35 (apps can still choose their own targetSdk regardless of RN version)
