Explicitly install Chrome version required by Puppeteer in CI

[sanason]

Fix the tests that are failing here with error message:

Error: Could not find Chrome (ver. 128.0.6613.119). This can occur if either
1. you did not perform an installation before running the script (e.g. npx puppeteer browsers install ${browserType}) or
2. your cache path is incorrectly configured (which is: /home/runner/.cache/puppeteer).
For (2), check out our guide on configuring puppeteer at https://pptr.dev/guides/configuration.

Two parts to this fix:

1. Add a CI step to explicitly install the browser version required by Puppeteer. Previously, this was handled by a postinstall script in the puppeteer package. However, recent versions of npm have started to disable install scripts by default. See discussion here.
2. Update the puppeteer version. After adding the CI step, I encountered the bug described here. Upgrading puppeteer fixed the problem.
