chore: let Webpack to manage CatalogUtils.js

This makes possible to use Jest for JavaScript unit tests.

The public URL of DateUtils.js has been changed
from /public/js/$VERSION/CatalogUtils.min.js
to   /public/js/$VERSION/utils/CatalogUtils.min.js
and technically old cached code might search by the old location but as this file wasn't available
to anonymous users, the chances are extremely low.
