feat: add delay for SSH server readiness in CI

Introduced a step in the CI test workflow to wait for the SSH server to start before proceeding with subsequent actions. This ensures that the server is fully operational and can accept connections before any attempts are made to copy the public key into the Docker container, avoiding potential race conditions where the server might not be ready in time, leading to failed CI runs. The addition of a simple loop with a timeout mechanism improves the reliability of the CI pipeline by making sure tests only run when all services are up and running.
