Use .NET SDK sourcelink integration (#5764)

* Use .NET SDK source link integration

Fixes NuGet/Home#13410

Also set a required minimum version of the .NET
SDK so that we can be sure that the sourcelink
feature is available. Building with a newer SDK
is of course still possible.

* Update global.json
