Review EngHub for verbiage discrepencies

We need to refine the terminology used in our Release Planner and EngHub to better align with the way our development teams think about SDKs and services. Specifically, we should avoid using the term "Product" and instead focus on "Versions" of services and SDK packages. This will help ensure clarity and consistency across our documentation and planning tools.
