Run .NET globalization-invariant in the QUIC dev image

The interop lane's dotnet build FailFasts on startup in this minimal Debian
image: no ICU package, and .NET's globalization stack aborts without one
rather than degrading. The interop peer already parses every argument through
CultureInfo.InvariantCulture, so invariant mode costs it nothing; it is also
Microsoft's own documented fix for a minimal container, cheaper than pinning
and installing an ICU package by name.
