Add a changelog check to CI

[Tompage1994]

Is your feature request related to a problem? Please describe.
The changelog sometimes fails because incorrect keys are used etc. We should add a check that validates the changelog is actually going to work

Describe the solution you'd like
A step which just runs the changelog command to verify. Probably antsibull-changelog lint

Thinking about it, it's probably a change which needs to be made to https://github.com/redhat-cop/ansible_collections_tooling/tree/main
