Using `--jsonfile` switch of `dotnet-install.sh` fails with some roll forward policy

[atifaziz]

I have a project with the following global.json:

{
  "sdk": {
    "version": "3.1.101",
    "rollForward": "latestFeature"
  }
}

Using dotnet-install.sh with the --jsonfile option produces an invalid download URL of the form: https://dotnetcli.azureedge.net/dotnet/Sdk/3.1.101rollForward:latestFeature/dotnet-sdk-3.1.101rollForward:latestFeature-linux-musl-x64.tar.gz

The problem is the 3.1.101rollForward:latestFeature path component of the URL.

Steps to reproduce in a Docker container running Alpine Linux 3.9:

❯ docker run --rm -it alpine:3.9
/ # apk add --no-cache -q bash
/ # wget -q https://dot.net/v1/dotnet-install.sh
/ # chmod +x dotnet-install.sh
/ # cat > global.json <<EOF
> {
>   "sdk": {
>     "version": "3.1.101",
>     "rollForward": "latestFeature"
>   }
> }
> EOF
/ # ./dotnet-install.sh --jsonfile global.json --dry-run
dotnet-install: Payload URLs:
dotnet-install: Primary named payload URL: https://dotnetcli.azureedge.net/dotnet/Sdk/3.1.101rollForward:latestFeature/dotnet-sdk-3.1.101rollForward:latestFeature-linux-musl-x64.tar.gz
dotnet-install: Repeatable invocation: ./dotnet-install.sh --version "3.1.101rollForward:latestFeature" --install-dir "/root/.dotnet" --architecture "x64"

Hi @atifaziz ,
Thank you for the issue. Since we are already tracking this in #7, I will close this one.
