fix: kong stops responding

kong easily gets overwhelmed when receiving many requests, resulting in an error complaining about not having enough workers. This was due to KONG_NGINX_WORKER_PROCESSES=1 being set. Kong automatically determines the right number of worker processes (1 per allocated CPU) when this is not specified, which resolves the issue.
