Git Clone Is Not Allowed Anonymously In GitHub with SSH

[ZianAtFirstWatch]

As described at https://stackoverflow.com/a/46993922, when I run
git clone git@github.com:koopjs/koop-sample-app.git
(from https://koopjs.github.io/docs/basics/quickstart)

Then I get:

The instructions should tell people to something like use
git.exe clone --progress -v "https://github.com/koopjs/koop-app-example.git" "c:\koop-app-example"

instead.
