Too many discards is now also a problem in conformance

Today [on CI](https://github.com/IntersectMBO/cardano-ledger/actions/runs/12956079753/job/36144218400#step:14:683) I ran into this failure:

```

This needs fixing otherwise it is gonna nag us forever as the old tracing testing system still does occasionally
