feat(docs): Document the image requirements

[gaocegege]

We need an http probe route in the container localhost:port/

Or the HTTP probe will fail.

I would love to work on this issue, Can you assign it to me and also I would like to know how to proceed with this issue @gaocegege

[gaocegege]

We should add a section in https://docs.open.modelz.ai/deployment/deploy or somewhere, to tell users that the image should run a single-port http server, and provide a http healthz check endpoint. We will use "/" by default.

BTW, we already support mdz deploy --probe-path /healthz.
