PATCH: handle keywords in ansible-doc completion

[Oliver Kiddle <opk@zsh.org>]

When listing available keywords, a trailing colon is included which is
unwanted when passing a particular keyword to ansible-doc. This stips
the trailing colon.

Also, --step is valid for ansible-playbook and had got left out.
