Unify RNTester Cache Policy Image example (#51580)

Summary:
The Image component in Android now supports the same cache control behaviour as in iOS, the examples needed to be separated in the past because the support was not the same for iOS and Android, but now that it is, we can unify the example.

## Changelog:
