Creating subcommands

Hi,
Thanks for a very useful tool!

I can't seem to figure out how to create subcommands like `$ docker container rm .`

If i try adding the path: /container/rm/{containerName}, the command will be created as `$ docker container-rm `

This is the first time that I am using both OpenAPI and this tool, so I am in no way an expert.

Thanks!

The issue names no files, tests, or entry points. Start by tracing how the path /container/rm/{containerName} is converted into generated command names, then determine how nested subcommands should be represented. Done means generating a command structure equivalent to `docker container rm ` without collapsing the subcommand path.
