Update template/android and RN Tester to use hermes-engine from the react-native NPM package. (#33467)

Summary:
Pull Request resolved: #33467

We can now change the `hermes-engine` dependency to be consumed by the `react-native` NPM package
and not anymore from the standalone `hermes-engine`. This will allow for a better stability
as the `hermes-engine` and the `react-native` were built from source at the same instant in time.

Changelog:
[Android] [Changed] - Update template/android and RN Tester to use `hermes-engine` from the `react-native` NPM package.
