Puppeteer tests are not working on Github Actions

The Puppeteer tests were added in https://github.com/dart-lang/webdev/commit/829a74ba7a2954f35a60ea827303f692c922d916, and all passed. See https://github.com/dart-lang/webdev/actions/runs/3431310326/jobs/5719308010

However, the `setUpAll` step is now failing on Github actions, although it passes locally. Here is the error:

```

Increasing the test timeout did not fix it. I think there is probably some setup required in our Github actions workflow.
