feat: implement the Puppeteer CLI

[OrKoN]

This PR implements the CLI for Puppeteer. It is a variation of the @puppeteer/browsers but unlike @puppeteer/browsers it is stateful because it will resolve the Puppeteer's pinned browser versions and prefer them over the latest versions. So the version that is downloaded and the cache folder is determined by Puppeteer's configuration and might be different from a project to a project. It's recommended that you use the Puppeteer CLI in the context of your Puppeteer project and don't install it globally.

Usage

Install Puppeteer into your project if you don't have it installed yet:

npm install puppeteer

Launch the CLI:

npx puppeteer browsers --help # get help message
npx puppeteer browsers install chrome # installs the pinned version of Chrome
npx puppeteer browsers install firefox # installs the pinned version of Firefox (currently, it's the nightly though)
