* Re-add MSBuild darc NuGet source needed for Microsoft.Build 18.6.4

The codeflow automation incorrectly removed the
darc-pub-DotNet-msbuild-Trusted-13cd968a NuGet source while
Microsoft.Build.Framework 18.6.4 is still referenced in
Version.Details.xml. This package is not available on any standard
feed (nearest stable is 18.4.0 on dotnet-public), causing NU1103
errors across all CI jobs.
