[REQUEST]: Prepare public documentation for the distribution helper tool for Package Registry

[jsoriano]

Description

We are introducing a new tool to help creating Package Registry distributions.

This helps solving a usual concern with the big size of our published distribution images. This new tool helps maintaining custom images with the packages each user needs.

Resources

This tool is being introduced on these PRs, that include reference docs:

• Tool to help creating distributions of packages package-registry#1335
• feat: Add custom Docker build for package registry package-registry#1554

Collaboration

TBD. The docs and product team will work together to determine the best path forward.

Point of contact.
