puppeteer used by headless Chromium is being developed fast. Given how it hasn't hit a stable milestone, we should also updated it as part of the chromium-render service. This task is about finding a general way of updating puppeteer and updating it to the latest version too.
A/C
- update puppeteer to the latest version
Done in rMSCR9c786153200f: Puppeteer: update to version 0.13..
- set up a process to track updates to the puppeteer (calendar invites? add it to chore list? or anything else?)
