chg: [information-origin] create a new taxonomy define if the content is

from an AI-based system, a human or the origin is unknown.

The original taxonomy from @aaronkaplan has been fixed to match
the correct MISP taxonomy schema format. The file in the original pull-request
was most probably `information-origin:AI-generated`.

This taxonomy is just namespace predicate as there is no need of
specific values until now.
