Thanks! I've added the reason. (// Docker CLI does not provide a standalone healthcheck command.)

`docker ps` displays the health check results for healthchecked containers in the STATUS column: ```bash $ docker run -d --name health --health-cmd=true --health-interval=3s alpine sleep inf ace14dd125355ac04e8cbad9f1cf2eaaa7209d76cb648ccefb81e45b986c58f7 $ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ace14dd12535 alpine "sleep inf" 23 seconds ago Up 22 seconds (healthy) health ``` However, `nerdctl ps` doesn't show the health status. Therefore, to ensure compatibility with Docker, this change makes `nerdctl ps` display the health check results in the STATUS column for containers that perform health checks. After this change, the output looks like: ```bash $ sudo nerdctl ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 02c64243528a docker.io/library/alpine:latest "sleep inf" 7 seconds ago Up (health: starting) hoge ``` ```bash $ sudo nerdctl ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 690aa502978c docker.io/library/alpine:latest "sleep inf" 1 second ago Up (healthy) hoge ``` ```bash $ sudo nerdctl ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 02c64243528a docker.io/library/alpine:latest "sleep inf" 2 hours ago Up (unhealthy) hoge ``` Signed-off-by: Hayato Kiwata <dev@haytok.jp>
