Improve documentation show case while doing completion

Description

At the moment when I try to complete in ZSH:

$ scw
\              account        apple-silicon  baremetal      cockpit        container      document-db    fip            help           info           instance       ipfs           lb             mnq            rdb            registry       shell          version        vpc-gw                                                                                                                                                                                                                                      
--             alias          autocomplete   billing        config         dns            feedback       function       iam            init           iot            k8s            marketplace    object         redis          secret         tem            vpc            webhosting  

let's compare that with other well known CLI such as kubectl in ZSH:

And in fish:

How I imagine scw could expose this functionality

When I type a TAB, in the suggestions I would get the documentation string. It might not be possible in all shells but it would help in modern and dev focused shells such as ZSH and fish
