Also I am confused about the intent of the PR in general, why not using githubgen for this? Can you please clarify why we need this feature.

We use the list of distributions to render the list with hyperlinks in the README of components presently.
We have moved the list of distributions to a centralized yaml file at the root of the repository, which is used to generate a distribution report under report/distributions.

This closes the loop on the change, by adopting the distribution data from the yaml file as the source of truth for component distributions. This allows us to maintain distributions by editing distributions.yaml and see it reflected in all READMEs and distribution reports. See #29697 for context and #28628 for the original motivation.

@dmitryax please review as codeowner?

How this change will play with the fact that mdatagen is moved to core? I think we need to start planning the deprecation and removal of this package from contrib
