Automatically generate CHANGELOG

[Urhengulas]

It would be great if we could automatically generate our CHANGELOG.md instead of maintaining it by hand.

There are a few tools for that, one of them being git-cliff¹. It would make sense to use it, since it is integrated in release-plz², but we disabled it at the moment.

We could update the CHANGELOG for every commit being released on master, but I think it makes more sense to just do it on the release. Also this is the behavior from release-plz.

The problem with git-cliff is that it expects conventional commits³, which we do not have and therefore it generates a broken CHANGELOG. So we need to configure it through the git-cliff.toml in a way that it can handle our commit messages.
