This PR adds configurations files to `puppeteer`'s methods for
configuration. Under the hood, `puppeteer` relies on
https://www.npmjs.com/package/cosmiconfig which resolves several formats
of configuration:
- a `puppeteer` property in package.json
- a `.puppeteerrc` file in JSON or YAML format
- a `.puppeteerrc.json`, `.puppeteerrc.yaml`, `.puppeteerrc.yml`,
`.puppeteerrc.js`, or `.puppeteerrc.cjs` file
- a `puppeteer.config.js` or `puppeteer.config.cjs` CommonJS module
exporting an object
Documentation will be added later.
Fixed: #9128
