Please re-add showing the span id in trace view.

<!-- Please only use this template for submitting feature requests --> **Why is this needed**: When looking at the expanded view of a span, it was possible to see the span ID in the bottom right. This information being quickly visible was such a nice feature when trying to find correlating data between observability tools. It also helped us track down when there were duplicate span IDs. Now I either have to export the span to JSON, or examine the URL provided in 'share' button. I understand space is a premium when showing such informationally dense data, but to me this seems like too an important thing to lose. **What would you like to be added**: Just go back to showing the span ID in the expanded view, please. **Who is this feature for?** People who like to see detailed information in their trace data, which I imagine is most people? Especially SREs or observability teams responsible for good trace data. Thanks for your consideration :)
