Collection.__getitem__ is supposed to only support string names, like this:

>>> coll = client.db.coll

>>> coll.name

'coll'

>>> coll["foo"].name

'coll.foo'

However in ~~PYTHON-3084~~ we discovered that it accidentally supports non-string names as well:

>>> coll[0].name

'coll.0'

>>> coll[{}].name

'coll.{}'

We should deprecate remove this behavior in PyMongo 5.0.
