Bug 28442: Update template for new roles

We have multiple accessibility advocates this cycle, so we needed to
adapt the template. I've also added the meeting facilitator as a case
but not added to the team block as a whole.. seeking opinions, perhaps
wait and see if it lasts more than a cycle before adding it fully?
