text: Title: Newest release of Chromium
  Body: Hi,
  
  The pyppeteer's docs say that `pyppeteer-install chrome` would install the latest Chromium release. In fact in Linux x64 environment the downloaded release was `588429`, while the actual latest release is `839847`.
  A manual update (replacing files) is possible and all is working fine with the latest Chromium release, so is there a way to upgrade or reinstall Chromium to the actually latest release using pyppeteer's setup tools?
  
  Thanks in advance.
