Add `update_many` method about wither HOT 3 CLOSED

@wbrickner thanks for anther great issue. You are correct that a model-level update_many does not yet exist in Wither, we should definitely add it. We have the same thing for delete_many, and adding update_many will be dead simple.

Right now, you can still do this directly via the mongo client (which uses this method):

Model::collection(&db).update_many(query_doc, update_doc, options).await?;

Once we add a wrapper for this method in Wither, your code would just look like:

Model::update_many(&db, query_doc, update_doc, options).await?;

from wither.

Would you be interested in contributing a PR for this?

I figured out how to do it via collection access. I will submit a PR for a few convenience methods like this one.
