Describe the bug

Step 3 from the Build ASP.NET Core from Source guide fails on Apple M1 silicon.

When I run ./restore.sh I get several errors that look like the one pasted below:

Unknown CPU arm64 detected, treating it as x64

dotnet-install: Note that the intended use of this script is for Continuous Integration (CI) scenarios, where:
dotnet-install: - The SDK needs to be installed without user interaction and without admin rights.
dotnet-install: - The SDK installation doesn't need to persist across multiple CI runs.
dotnet-install: To set up a development environment or to run apps, use installers rather than this script. Visit https://dotnet.microsoft.com/download to get the installer.
