PYTHON-5314 Fix default imports

Oddly, ruff complained about the existing code

# Public module compatibility imports
import pymongo.uri_parser  # noqa: F401 # isort: skip
import pymongo.change_stream  # noqa: F401 # isort: skip
...

But if I remove the noqa comment, ruff will delete the imports because it thinks they're unused...

The only way I found to avoid this was to change the imports to from pymongo import uri_parser.
