Leverage Gradle implicit dependency substitution for Gradle Plugin

Summary:
Previously we asked users to specify a dependency substitution
rule to properly use the React Native Gradle Plugin.

Here I'm updating the Gradle Plugins setup to allow to use implicit
dependency substitution. This requires to specify a Maven Group and Artifact
Name (through the project name).

This is backward compatible as users will still be allowed to specify a
dependency substitution rule if they wish.
