completion: clarify installation instruction for zsh

mbelsky · gitster · commit 176f5adfdb01 · 2019-10-18T13:55:49.000+09:00
The original comment does not describe type of ~/.zsh/_git explicitly
and zsh does not warn or fail if a user create it as a dictionary.
So unexperienced users could be misled by the original comment.

There is a small update to clarify it.
