Any plan to bring up the dotnet run file design spec/document to the dotnet/designs repo

@jjonescz @jaredpar thoughts? I'm not sure how we historically demarcate between dotnet/designs and the documentation in this or other repos for docs like this.

I also don't know what our demarcation policy is. Typically when a design invoked significant Roslyn and SDK changes we put it here. But that has also been for lower level items that aren't as directly customer facing as this feature. I don't have any objections to putting it on designs if we feel that's a better place
