Bump nexus-publish to 2.0.0 (#52566)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52566

This bumps the plugin we use to publish to Maven Central from 1.3.0 to 2.0.0
as it has better support for the latest Gradle feature.

We're not affected by the breaking changes so we should be good to go (nightlies will tell).
