docker doesn't error out on `docker missing-subcommand --version`

[ojab]

Description

AFAIU it's impossible to check if plugin is installed/subcommand is available (docker compose, for example), because

$ docker asdasd --version
Docker version 20.10.20, build 9fdeb9c

Without --version flag it correctly reports that subcommand is not avaiable.

Reproduce

1. docker asdasd --version without asdasd plugin installed
2. Docker version 20.10.20, build 9fdeb9c

Expected behavior

$ docker asdasd 
docker: 'asdasd' is not a docker command.
See 'docker --help'
$ docker asdasd --version
docker: 'asdasd' is not a docker command.
See 'docker --help'
