Fix NetRuntimeBlobVersion

[mthalman]

Fixes dotnet/source-build#4679

A regression was caused by the merge of #44257:

/vmr/src/sdk/src/Installer/redist-installer/targets/GenerateLayout.targets(410,5): error : Download from all targets failed. List of attempted targets: file:///vmr/artifacts/assets/Release/Runtime/9.0.0/dotnet-runtime-9.0.0-centos.9-x64.tar.gz [/vmr/src/sdk/src/Installer/redist-installer/redist-installer.csproj]
/vmr/src/sdk/src/Installer/redist-installer/targets/GenerateLayout.targets(410,5): error : Failed to download file using addresses in Uri and/or Uris. [/vmr/src/sdk/src/Installer/redist-installer/redist-installer.csproj]
    0 Warning(s)
    2 Error(s)

This is the same kind of error that occurred for an aspnetcore asset in #44196, which was fixed by 93f82c2. Following a similar pattern here to fix the issue for the runtime asset.
