Fix incorrect MSBuild property name in Azure test job

Change PackageVersionSqlServer to SqlServerPackageVersion in
test-azure-package-ci-job.yml. This job runs dotnet build directly
against Azure.Test.csproj (not build.proj), so the build.proj-level
PackageVersionSqlServer property was silently ignored. The csproj
consumes SqlServerPackageVersion via Directory.Packages.props and
Versions.props.
