Mac M1 issue with build

[qasimalyas]

The documentation states that we need version 5 of dotnet https://docs.microsoft.com/en-gb/learn/modules/create-a-build-pipeline/1-introduction but the mac m1 doesn't support this version. M1 support is added from dotnet 6.

While trying to run and build the app running this command dotnet run --configuration Release --no-build --project Tailspin.SpaceGame.Web fails.

A fatal error occurred. The required library libhostfxr.dylib could not be found.
If this is a self-contained application, that library should exist in [/Users/username/Projects/mslearn-tailspin-spacegame-web/Tailspin.SpaceGame.Web/bin/Release/net5.0/].
If this is a framework-dependent application, install the runtime in the global location [/usr/local/share/dotnet/x64] or use the DOTNET_ROOT environment variable to specify the runtime location or register the runtime location in [/etc/dotnet/install_location].

The .NET runtime can be found at:
  - https://aka.ms/dotnet-core-applaunch?missing_runtime=true&arch=x64&rid=osx.11.1-x64&apphost_version=5.0.13

Does the demo application need to updated with the latest dotnet version?
