Subject: [PATCH] Add liveness and readiness probes to Kubernetes configs

Introduced liveness and readiness probes for the Playwright service, API, and worker components. This ensures that Kubernetes can better manage the health and availability of these services by periodically checking their endpoints. This enhancement will improve the robustness and reliability of the deployed applications.
