Cypress step can hang in the CI

Ex: https://gitlab.esrf.fr/workflow/ewoks/ewoksweb/-/jobs/511914

This is due to pnpm dlx wait-on http://localhost:3000 never resolving.

My guess it that the port 3000 was not available so pnpm dlx serve ran the server on a different port (42033 in the linked example), preventing the wait-on to resolve.

Perhaps the app on the port 3000 is not cleaned-up fast enough when CI jobs are run in quick succession 🤷 ?

Might be worth running lsof -i :3000 on failure.
