schematelemetry: better redaction for invalid objects

[annrpom]

We log found invalid objects here

cockroach/pkg/sql/catalog/schematelemetry/schema_telemetry_job.go

Lines 141 to 151 in c64b755

	descID, ok := row[0].(*tree.DInt)
	if !ok {
	return errors.AssertionFailedf("expected id to be int (was %T)", row[0])
	}
	validationErr, ok := row[1].(*tree.DString)
	if !ok {
	return errors.AssertionFailedf("expected err to be string (was %T)", row[1])
	}
	log.Warningf(ctx, "found invalid object with ID %d: %q", descID, validationErr)

In our live-streamed logs, most of the information we need is redacted; so, we end up having to grab a debug zip

There might a better way to redact the validationErr so we do not have to do the dance above
