Profile/Timeline of build pipelines

After yesterdays edit to an event and the following hotfix, I had the subjective feeling that the regeneration of the webpages via the current CI/CD means takes quite some time (about 30 minutes). I would like to understand where this comes from and propose to generate a trace of the involved pipelines. This could then also be used for training purposes to build the correct expectation for the audience on how long CI-tests take.

For the presentation, I would suggest a typical timeline view.
