More human-friendly reports

During the summit talking about Ambassors, I came up with a idea of having the Weekly summarization of things that was merged on Node.

Wes Todd told me that we have this repo, and it already a great start, but I think if we could make it more human-friendly, we could send to the Ambassors to read and create content on things that will be on Node in the future.

I was thinking in using LLMs to grab the PR descriptions and titles and then generate a more friendly change about each PR merged.

What do you think?
