[compat api] Remove ContainerConfig field

[ninja-quokka]

ContainerConfig has been removed from v1.45

InspectResponse.Container has also been removed but it seems we never implemented it.

Ref: https://docs.docker.com/reference/api/engine/version-history/#v145-api-changes

Does this PR introduce a user-facing change?

GET /images/{name}/json no longer includes the ContainerConfig fields. To access image configuration, use Config field instead.

The way we handle the API docs makes it hard to correctly handle the compate API removals as users can't browse our API docs using docker version numbers.

I'm not sure what I should do, I can just make Container and ContainerConfig no longer show in the response json in the swagger docs?

Maybe this is a clean way: https://github.com/containers/podman/pull/27172/files#diff-591d6e4a5c080b38e1948fdf4ba7a35448f9d3845ef018c89a47eefadc7bf0adR26-R28
