Pin to Ubuntu 22.04 to fix Puppeteer

[smaye81]

From Puppeteer docs:

Ubuntu 23.10+ (or possibly other Linux distros in the future) ship an AppArmor profile that applies to Chrome stable binaries installed at /opt/google/chrome/chrome (the default installation path). This policy is stored at /etc/apparmor.d/chrome. This AppArmor policy prevents Chrome for Testing binaries downloaded by Puppeteer from using user namespaces resulting in the No usable sandbox! error when trying to launch the browser

We are currently seeing this error in CI due to our usage of ubuntu-latest in our CI Github Action images. It seems that Puppeteer has disabled this check as part of puppeteer/puppeteer#13196, but it doesn't look like this has been released yet. Once it has, we could potentially update to that latest version of Puppeteer and reinstate usage of ubuntu-latest. In the meantime, though, this pins our CI image to ubuntu-22.04 to get CI to pass.
