• Baselines that were testing net8 can probably be removed, and we add net11.
• Does crank work fine with net11 already?

1. That makes sense to me.
2. I am not sure, it looks like it is failing trying to restore packages. So we might need to update our NuGet.config. I am investigating now.

Looking at one class of test, GRPC, it seems like we use the nuget.config from the repo we get the scenario out of. How do we handle testing against latest bits? Looking at that project in particular they have never been on the latest packages. @sebastienros

Crank injects a custom nuget.config and/or patches the csproj to add the nightly feeds
