Compilation error regexes don't pick up panic backtrace file locations

[rtpg]

While working through something I noticed that while the panicing regex does pick up the "panicked at" line and put a link there, it doesn't properly capture the subsequent at lines.

checking "/Users/rtpg/proj/ruff/crates/red_knot_workspace/resources/test/corpus/73_class_generic_cycle.py"

   <etc>

This is probably an easy fix with the regex compilations, but having a bit of trouble finding the right incantation here
