opentf-ctl get workflow does not display events related to publication

Context:

As of today opentf-ctl, no matter the depth (step & job) of the wanted output, won't show events related to results publication -- to a test management tool for instance --. c.f. opentf-ctl-get-workflow-output.log even though they are displayed in the orchestrator logs.

My 2 cents guess is that the observer itself does not listen to such events. Hence those are not displayed when requested

Proposal:

opentf-ctl get workflow [workflow-id] should display all events related to a workflow including those associated to results publication.

Impacts:

If my guess is correct, one may have to modify the Observer to listen to the related events.
