Describe the bug

When using yarn create the version specifier doesn't work when the package is scoped. Example yarn create @angular@next.

➤ YN0001: │ Error: create-@angular@next isn't supported by any available resolver

@angular isn't a valid identifier, you'll have to run the following instead

yarn dlx @angular/cli@next new my-project --package-manager yarn

@merceyz, why not? @angular/create is a valid package that we just released as pre-release yesterday.

See: https://www.npmjs.com/package/@angular/create

Does this mean that Yarn 2 and 3 no longer support scoped packages when using yarn create?

[merceyz]

I see npm documents

npm init <@scope> (same as `npx <@scope>/create`)

so I'll add support for that as well.

Though note it doesn't actually work with npm

$ npm init @angular@next
npm ERR! code EINVALIDPACKAGENAME
npm ERR! Invalid package name "@angular" of package "@angular@next/create": name can only contain URL-friendly characters.

@merceyz, yeah I am aware of that. I have a separate issue for that npm/cli#5175
