Ease the process of generating the changelog for releases?

Description:

Today I learned that GitHub now offers a button to auto generate the changelog (release notes) when drafting a new Release: https://docs.github.com/en/repositories/releasing-projects-on-github/automatically-generated-release-notes

I think this could ease the process we have right now for generating the changelog when we create a new release.

I would like to see what it actually does and if it misses some bits we currently add to the changelog.

As an example, it generated this list when drafting a new release for Choclo:

Apparently it's not grabbing text from the descriptions of the PRs, something we usually try to include in the changelog. It also not splitting the changes into categories, but I think this could be done and configured by using labels in the PRs.
