chore: update changelog

breaking change comments where missing

can you just write into the changelog like that? I think it's generated from the commit history. These changes might just be overwritten. I think you can do this as an empty commit (--allow-empty) and then put the markdown into the commit message.

I did not write this manually but I regenerated the changelog with git-cliff using our config. This is what release-plz also uses internally. However it does not regenerate the whole changelog, but just adds a section for the new version. Thus the changes I made here should not be overwritten.
