Use Microsoft.NETFramework.ReferenceAssemblies instead of RoslynTools.ReferenceAssemblies.

There is actually a NuGet package called Microsoft.NETFramework.ReferenceAssemblies. It depends on smaller packages depending on the framework, that contain the actual reference assemblies separately per framework. Each of these packages weighs about 10 MB.

This would be a real fix of #2238. The smaller packages would unburden a subpar internet connection, and FAKE would stop depending on a cryptic dependency from a custom source.

Yep indeed I just was too lazy to change it until now. It's really a non issue for me as 100mb is not that much and it is only downloaded once...
But PR is definitely appreciated

Wait a minute, you had already fixed it in 33beb99. 😂

Ah didn't even look and apparently forgot about it :D
