Workflow failure when updating reference snapshots

[jtpio]

The workflow to update reference Playwright snapshots often fails, and needs to be restarted manually for the update to be completed: https://github.com/jupyter/notebook/blob/main/.github/workflows/playwright-update.yml

It sometimes fails because of the UI test flakyness (a different issue).

And sometimes because of the following error:

https://github.com/jupyter/notebook/actions/runs/9059110076/job/24886021429
