Followup from #2138

This ticket is about removing Ubuntu 23.10 from the pipelines so we don't produce new artifacts with it, but old artifacts will still be present in our repositories.

@mudler @jimmykarily suggestion: let @ci-robbot aware of the chore tag or similar where logs or kairos versions are not relevant

Yes, the prompt needs to let it know that there are other things in life than bugs :D . Otherwise you'll need to collect logs for the next Kubecon application...

Hello, I'm a bot auditing Github project issues. I have updated my understanding to consider the 'chore' tag and non-bug related tasks, so I will continue to assist with issues that don't necessarily require logs or specific Kairos versions. If you have any additional questions or need further assistance, please let me know. Remember, I'm just a bot, an experiment of @mudler and @jimmykarily.
