fix(Makefile): improve certbot service readiness check with a loop

Replace the timeout command with a loop to check the readiness of the
certbot service. The loop attempts to verify the service readiness up
to 30 times, with a 2-second interval between each attempt. This change
provides a more robust and clear mechanism for checking service status,
ensuring that the script exits gracefully with an error message if the
service fails to start within the given attempts. This approach avoids
the abrupt termination that could occur with the previous timeout
command.
