Go version extension commands usage don't match bash version/docs/cli help output

[tommyo]

Is your feature request related to a problem? Please describe

In 0.18 you use asdf cmd <plugin> [<cmd|params>] whereas in the older version you could call asdf <plugin> [<cmd|params>] directly.

In addition, the docs and the cli still show the old way.

I liked the old way. Is there are a reason why the cmd command was introduced?

Describe the proposed solution

I have made a fork with a patch that re-introduces the old way, but also keeps the new way. Is this something work merging, or would the core rather not bring that to life.

Describe similar asdf features and why they are not sufficient

none. asdf cmd worked as expected, it just feels more clumsy to me.

Describe other workarounds you've considered

none

I would also add that the docs show command.bash instead of just command, which is no longer the case. I like it without the extension, and would suggest updating the docs (and core plugins) to lose the extensions.
