There was a warning when running `npm install` in Action View:
coffee-script@1.11.1: CoffeeScript on NPM has moved to
"coffeescript" (no hyphen)
We are not requiring `coffee-script` explicitly, but `coffeelint` does.
The latest version, 2.1.0, already fix the dependency package name, so
we should upgrade to it to suppress the warning.
Together, fix to the following lint violation.
```
rails/actionview/test/ujs/public/test/data-confirm.js
303:11 error Strings must use singlequote quotes
rails/actionview/test/ujs/public/test/data-remote.js
