docker: add caveats

[osalbahr]

The added caveat should clarify how to add the CLI tools after installing the cask.

Fixes #46078 (comment)

• The submission is for a stable version or documented exception.
• brew audit --cask --online docker is error-free.

I like your updated caveat. It's more concise and conveys more information.

I just tried to install the cask just to see how it would look like. Is the newline before "based" intended?

Thank you! Yes, the line break was intentional as not all terminals line-wrap. I'll change it in the next update so it breaks at 80 char instead of 100.
