Subject: [PATCH] Normalize stack trace file locations

The stack traces paths are significantly shorter, and only show the
relevant path fragment.
Before:
/home/runner/work/Multiplayer/Multiplayer/Source/Client/Desyncs/DeferredStackTracing.cs:41
After:
Multiplayer/Client/Desyncs/DeferredStackTracing.cs:41

See https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/compiler-options/advanced#pathmap for docs.
Despite the warning, breakpoints still do work (at least for me).
