Feature: Rollup changelog

Enter your suggestions in details:

At Colalb Summit, @ljharb and I discussed better ways to showcase notable changes between versions.
We envision a user feature that could aggregate the notable changelog entries from X version to Y version, helping users better understand new things.

This could also be an opportunity to surface any relevant @nodejs/userland-migrations or perhaps EOL content options.

I’m envisioning a UI component with two dropdowns that list all node versions on every changelog page, and when you click the button, it takes you to a page that summarizes all the notable changes between those versions (which also has the dropdown component at the top).

To do this, we'd also need a way to grab the changelog of each release and it's changelogs and/or release notes. We could read it from the blog posts?

This can be compared to guided migrations #8053

Furthermore, for userland migrations, I still have difficulty finding the breaking changes that we need to cover. Such a list would be helpful.

We can search this manually via the semver-major label, but that's not ideal.
