[Announcements] Show which sections have been assigned an announcement

[ezaurova]

Problem statement:

Currently, if a co-instructor has created an announcement but only for their sections, it's not obvious from the announcement. You need to go to the Announcements page to see which sections have been assigned which announcement. However, many instructors may erroneously assume an announcement has gone out to everyone in the course, thereby thinking their students have already seen the message

Proposed solution:

Just do a similar thing you do in the Announcements page. Somewhere in the announcement it should say which sections the announcement is visible to. It could be next to the date information, so it looks like Created xx xx xx | Posted xx xx xx | Section(s), or just under it.

User role(s):

instructor

As you can see, there's no information about which sections can see this announcement.  However, if I go to the Announcements page, I can see it.

Just most people wouldn't think to go there to see who the announcement was made to.
