JoelEinbinder f2b6016354 chore: switch to npm from yarn (#1878) 
This patch:
- migrates CI to use NPM
- drops lockfiles (`yarn.lock`). Lockfiles are ignored by package
  managers when the package is installed as a dependency, so this makes CI closer to the 
  installation our clients run.

Running the examples

Assuming you have a checkout of the Puppeteer repo and have run npm i (or yarn) to install the dependencies, the examples can be run from the root folder like so:

NODE_PATH=../ node examples/search.js

Tips & Tricks

Load a Chrome extension

By default, Puppeteer disables extensions when launching Chrome. You can load a specific extension using:

const browser = await puppeteer.launch({
  headless: false,
  args: [
    '--disable-extensions-except=/path/to/extension/',
    '--load-extension=/path/to/extension/',
  ]
});
