Updating a date field using update([]) does not convert it to mongo date. #2177

Description:

Updating documents with the ->update() method saves Carbon dates as Object instead of Date in the database. Doing the same using ->save() on a model works fine. Yes, the models have the property registered as a date in the $dates array.

Steps to reproduce

1. Create model with property 'end_date'. Add property to $dates array on the model.
2. Create date $date = Carbon::parse('2021-01-08 10:00');
3. Run query: Model::where('match', true)->update(['end_date' => $date]);
4. Check db.

Expected behaviour

The end_dateshould be saved as a field of type Date instead of Object

Actual behaviour

end_date is saved as object

Additionally, if you were to do ->update(['end_date' => $date->toIso8601String()]) the date would be saved as a String field
