Announcing core Node.js support for ECMAScript modules

It was a difficult process, but I am very happy that Node finally has support for unflagged native ESM. It landed today in Node 13.2. Thank you for everyone who worked on this.

The `modules` team still continues to work to improve ESM support, especially for packages wanting to provide both formats ("CommonJS" and "ESM") during the transition.

I recommend following the discussions on the nodejs/module repo [0] for anyone interested.
