Create a Blazor WASM sample

### Describe the Problem

We currently have samples for standard ASP.NET Core apps. However, Blazor WASM apps are unique in that the build output is a static site, not a `.dll` or executable that can be run with the `dotnet` cli. Our existing ASP.NET Core samples won't work for Blazor WASM apps.

### Describe the Solution

We should create a Blazor WASM sample app and provide example Dockerfiles for building and deploying it using a static web server using IIS, nginx, Apache, or python (or whichever other server, perhaps even a simple .NET one). Additionally, we should point to the Azure and GitHub docs for deploying static sites.
