[Infra] Show dotnet-install progress

On an average internet connection, running Restore.cmd will take a relatively large time to download the required version of the .NET SDK.

D:\dotnet\Roslyn>Restore.cmd
dotnet-install: Downloading link: https://dotnetcli.azureedge.net/dotnet/Sdk/5.0.100-preview.7.20366.6/dotnet-sdk-5.0.100-preview.7.20366.6-win-x64.zip

I think it’s a better experience of a progress or something is shown.

I wasn’t able to transfer it using Github’s feature, but Zenhub’s worked. dotnet/install-scripts#77

https://github.com/dotnet/install-scripts is the correct place for install script related issues (I don’t have the permission to move it myself). Thanks.
