Enable Artifacts output layout (https://learn.microsoft.com/en-us/dotnet/core/sdk/artifacts-output)

• we no longer own customizing output paths
• The default layout meets most needs that called for custom output paths to begin with
• can be customized further if needed
• folder paths are also much more consistent and predictable
