Resolve issue: #2413, add --cpus to docker update method

[pkruk]

Hi,

In this patch I've added a missing missing '--cpu' parameter for a docker update command.

I followed the docker documentation: https://docs.docker.com/engine/api/v1.29/#operation/ContainerCreate and PR: https://github.com/moby/moby/pull/31148/files

This PR should solve a issue: https://github.com/docker/docker-py/issues/2413
