What is the problem you're trying to solve

I was trying the docker/logs-explorer-extension with nerdctl instead of docker and found that it would call nerdctl inspect '--format={{json .}}' --size=false ..., which fails because nerdctl doesn't support --size.

The option is documented at https://docs.docker.com/engine/reference/commandline/inspect/#size

Describe the solution you'd like

It is rather low priority, but it would be nice if the option was implemented for docker compatibility.

Additional context

Note that adding support for --size alone would still not allow using the docker/logs-explorer-extension with nerdctl; it would also require #54 because it also runs nerdctl events --filter type=container --format '{{json .}}'
