[Feature] Support ES module syntax

[davidgilbertson]

I'm using ES modules with Node 14. I can import Playwright like this:

import playwright from 'playwright';

const { webkit } = playwright;

But not like this:

import { webkit } from 'playwright';

This is because the build is CommonJS format, with no ES module variant. Which I guess is because you're using Webpack. For this feature request, you'd need to either switch to Rollup (IMO a better fit for npm packages) or wait for Webpack to support it (it's in the works for V5).

Doesn't the esModuleInterop flag in webpack also allow that style of import?

@GeorgeWL could you elaborate? Are you referring to Webpack in the build of Playwright? Or are you proposing that users of Playwright use Webpack to transpile their code?
