Unify Gradle repositories

[wzieba]

Description

This PR unifies configuration of repositories for modules in the project via dependencyResolutionManagement. It's already used in WP/JP app without any issues: wordpress-mobile/WordPress-Android@c009a79 and I've recently, by an accident, spotted the discussion (#13052 (comment)) about this issue in one of the PRs.

Lastly, this will help with #13304.
