Current rule to edit publisher fields (comment, ...) is to have the editor
group. However when having only portal, this group does not exist. The
feature should work as a standalone feature without depending on website.
The rule is then updated as follow: either the current user belongs to the
editor group (if it exists), either it can write on the related record
(given res_model / res_id).
Currently no crash in standard addons occur because its main usage is in
eLearning application, where editor can answer and update publisher comment
from the frontend (course review).
