Update a help center collection. Changing targetAudience, baseAudienceFilter or
extendedAudienceFilter also re-applies the resulting audience filter to every article in this
collection and, recursively, to all subcollections and their articles.
Bearer <token>.Who can read the collection. New collections default to all; an update that leaves it out keeps the current audience.
Create only: the help center site of a new top-level collection (a site id, or default).
A sub-collection always gets its parent's site; updates ignore it (PUT /helpcenter/sites/{id}/collections moves).
Ok
