Upgrade to latest Puppeteer #114
Description
As noted in #18, we have been using an older version of Puppeteer to avoid caching issues in our GitHub Actions build. We should be using a newer version of Puppeteer, which means we will need to figure out the correct way to cache. It should be a matter of updating the puppeteer config file to use a local .config/puppeteer folder for downloading the Chromium binaries and adding a caching step in the GH Actions workflows.
