fix: point node to the common js build

[jquense]

fixes #84 in a disappointing way

But there is a proper fix, which isn't that much difficult to implement.

Here's how I've fixed ESM for react-bootstrap/dom-helpers: https://github.com/react-bootstrap/dom-helpers/pull/180

Once dom-helpers are fixed, the same can be applied to this repo.
