op-challenger: clarify the output

[DenseDenise]

For my first time to use ./bin/op-challenger list-claims The data name really confuses me, after I check the spces, I found the index means for Trace_Index, we should clarify it. And the parent for the root shouldn't be NIL, Because of the missing data, I mistakenly thought that Parent Depth was a whole data, not two data.

The reason for adding the hyphen is that without it, attributes with spaces in the middle can easily be misunderstood as two separate attributes rather than one whole attribute. As for the alignment, the arrangement on my CLI is basically the same as before, so there shouldn't be any misalignment. As shown in the picture. @ajsutton

ah yeah I can see the new names still fit within the allocated space so the line format doesn't need changing. I'm definitely not a fan of adding in underscores - they just add more visual clutter. I'd also keep Value instead of Claim Value since all of the values are clearly from the claim.

I would also suggest just using Trace instead of Trace Index to keep it shorter - the values make it clear that it's a trace index. And a - instead of N/A for the root parent would reduce clutter a lot.
