Auto merge of #69042 - yaahc:backtrace-header, r=<try>

Remove backtrace header text

Fixes point 3 from #65280

related to #53487

This should probably be double checked by someone who works on fuschia because theres some extra fuschia specific output in `add_context` that is also removed by this change.
