Blazor Desktop docs plan

[Eilon]

Sooner we need:

• Getting started (building first app)
• Walkthroughs
  • Publishing an app
  • How to debug the WebView

And later consider:

• More advanced scenarios

Look at Mobile Blazor Bindings docs for inspiration (though all the native UI stuff doesn't apply, of course):

• Docs: https://docs.microsoft.com/en-us/mobile-blazor-bindings/
• Docs sources: https://github.com/MicrosoftDocs/mobile-blazor-bindings
