Enhance Documentation for Custom Registry Usage

[dianannperla]

Overview

While the current README provides a good introduction to setting up and using the RingCentral Micro Frontends framework, it lacks detailed instructions on how users can set up and use a custom registry for managing remote entry versions, which is mentioned as a feature in the documentation.

Suggested Improvements

I propose adding a dedicated section in the README that outlines the steps for configuring a custom registry, including:

1. Setting Up the Custom Registry: Instructions or examples on how to create and configure a custom registry.
2. Usage in site.config.js: A clear example of how to reference the custom registry in the site.config.js (or site.config.json) file, including sample configurations.
3. Publishing to the Custom Registry: A brief guide on how to publish your micro frontends to the custom registry.
4. Updating Dependencies: Information on how to handle version updates and dependency management using the custom registry.

Including this information would provide users with a clearer understanding of how to leverage this feature effectively, enhancing the overall usability of the framework.

Benefit

This enhancement will not only help new users to quickly implement a custom registry but will also improve the documentation's completeness, contributing to a better onboarding experience for developers.
