Updating puppeteer to support newer Chrome features

Recently I tried to render a page that uses the newish CSS `aspect-ratio` and the resulting screenshot doesn't recognize it. I suspect the reason is that this project is pinned to puppeteer v2 which predates Chrome support for `aspect-ratio`.

Puppeteer is currently on v19 and it looks like Chrome added support for `aspect-ratio` around the time Puppeteer v13 was released. I tried updating package.json to newer versions but the API in those newer versions has changed (in ways I have not studied closely yet) so the app errors out.
