Updating multiple documents

Sometimes, multiple documents need the same update: when correcting an error or tagging records that meet certain conditions, for example. That's where .update_many() comes in.

In this exercise, you'll use it to tag Oscar-winning movies that also have a rating above 7.0 as favorites.
