As spotted in https://github.com/openshift/openshift-docs/pull/70512/files#r1484644485.

I had to remove the 'cols' header when troubleshooting a build issue.

I can try adding it back again (I had to remove one column since then, so it might work with the 'cols' back in this time).

Let the merge reviewer know about the outcome.

Also, lowercase <trace_id> according to https://github.com/openshift/openshift-docs/pull/70512/files#r1486007137.
