Allow private npm packages as templates

Is your proposal related to a problem?

No. I just had to create a project like CRA in my work and we allowed private repositories. I want to know if it is a thing that the CRA community wants in the CLI. If it’s ok I could work in a PR.

Describe the solution you’d like

probally a flag like:

npx create react-app --template some-template-name --npm-access-token="123"

I discovered the problem. The template path within node_modules was not being found. I made the pull request with the following adjustment:

javascript:

create-react-app/packages/react-scripts/scripts/init.js

befor:

const templatePath = path.dirname( require.resolve(${templateName}/package.json, { paths: [appPath] }) );

after:

const templatePath = path.dirname( require.resolve(${templateName}/package.json, { paths: [${appPath}/node_modules] }) );
