Remove old changelog fragments

[mariolenz]

SUMMARY

There are some old changelog fragments still around that I think should be removed. I also think changelog fragments should be automatically removed when a new changelog is created.

ISSUE TYPE

• Feature Pull Request

COMPONENT NAME

changelogs/config.yaml

ADDITIONAL INFORMATION

I wanted to propose a new major release, but I ran into so many issues in #429 that I decided to split those changes into several PRs.
