The VMR currently puts some of the final artifacts under artifacts/<arch>/<configuration>/.... This includes the source-build tarball and other artifacts but none of the nuget packages (which are missing when not building from source).

It would be good to change that to the Arcade convention which is artifacts/packages/<configuration>/<Shipping|NonShipping>/ so that we can use the default Arcade templates for publishing artifacts to the pipeline and for publishing to BAR.

As part of this, the README.md should also be updated.
