Steps to reproduce

Run create-react-app referencing a template in a scoped package: npx create-react-app@next --scripts-version=@next --template=@klasbj/cra-template-scoped app-name

Expected behavior

The app should have been created based on the template in the scoped package.

Actual behavior

create-react-app tries to instantiate the project based on the NPM package cra-template-@klasbj/cra-template-scoped instead, which obviously fails.

Full output:

$ npx create-react-app@next --scripts-version=@next --template=@klasbj/cra-template-scoped app-name2
npx: installed 91 in 19.44s

I didn't let it connect to github, hence the errors in the middle.

Reproducible demo
