CI for macOS and windows always fails

Nobody has claimed this yet.

Describe the bug
mac and windows test runners always fail for all PRs, no matter if the PR in question has no issues with it. The failure is because the runners are crashing, which cancels all other test runners in the process.

Some thoughs:

@eitsupi has noted that the node version is very old (latest release is 22, we are on 16)
https://github.com/GabrielBB/xvfb-action has been deprecated, a potential replacement is https://github.com/coactions/setup-xvfb

Start by examining the CI configuration that runs npm run test on macOS and Windows, then reproduce the failure shown for GabrielBB/xvfb-action@v1.0. Compare the deprecated action with coactions/setup-xvfb and review the Node.js version used by the runners. Done means the macOS and Windows jobs complete successfully without cancelling other test runners.
