Support Source Generators in Notebooks

[JasonBock]

Is your feature request related to a problem? Please describe. It's not a problem, just something I'd like to see work in a notebook.

Describe the solution you'd like I noticed that if I reference a NuGet package in a notebook where that package contains source generators, the generators won't execute. Therefore, I can't use the package as intended. I'd like to be able to demo/document source generator packages using a notebook, so hopefully this will be supported in the future.

Note: @jonsequitur mentioned I should add this as an issue, so....here it is :)

Describe alternatives you've considered No alternatives.
