Proj0805: Define version for PackageReference

<PackageReference> nodes require a version number in order to properly resolve the package. This can be done by either using the Version attribute on the <PackageReference> node, or by using a matching <PackageVersion> node. The latter solution is required when Central Package Management is enabled.
