unhide probe name during detection run

e.g. when realtoxicityprompts.RTPThreat has finished running, the screen shows this, which doesn't tell us which probe is currently being processed:

realtoxicityprompts.RTPSexually_Explicit                                  toxicity.ToxicCommentModel: PASS  ok on 1000/1000                            
detectors.toxicity.ToxicCommentModel:
