Setup publishing of snapshots using io.github.gradle-nexus.publish-plugin

Summary:
This sets up publishing of -SNAPSHOT verison of Yoga using the
Gradle plugin `io.github.gradle-nexus.publish-plugin`

This plugin will take care of setting up the credentials for Sonatype and hitting the Maven repository.
I've cleaned up the setup and centralized it inside a script plugin in the `build-logic` folder so we can easily add more module and just use `id("publish")` to publish them as well.
