Nightly interop CI failures

[fippo]

https://github.com/webrtc/samples/actions has been failing the interop tests pretty consistently.
However, cloning the exact same code into a private repo I have works without any issues.

fippo/samples-ci-debug#1 -- same code works without errors there...

[fippo]

aha, a possible difference: in this repo Ubuntu 24.04.1 LTS is used while in the other repo it is still 22.04.5

[fippo]

actions/runner-images#10636 -- 24.04 rollout started on December 5th which roughly correlates with the failures starting to happen on December 8th. Lets pin to 22.04 to unbreak the tests

May explain another issue I saw with a PR test failing.
I can't remember seeing a notification of the failure. Who gets notified on such failures?

Still needs some investigation about why it fails on 24.04 - most likely changed chromedriver/geckodriver path

If I read
https://docs.github.com/en/actions/monitoring-and-troubleshooting-workflows/monitoring-workflows/notifications-for-workflow-runs
correctly those failures will go to me (well, I filter them) you might have to make a commit with the webrtc-dev@ email...

Some progress:

• mapVersion is missing the "browser" argument. Oops.
• Chrome fails to start. I can reproduce this locally when using BROWSER_A=chrome BROWSER_B=firefox BVER=unstable DISPLAY=:99.0 node test/download-browsers.js without running Xvfb. This suggests the issue with related to xvfb
