The `urllib3.request` module was removed in urllib3 v2.0.0, and `RequestMethods` was moved to a private module `urllib3._request_methods`.

This commit updates the docstrings in `google/auth/transport/urllib3.py` to remove references to the now-private `urllib3.request.RequestMethods` class. Instead, it references the public `urllib3.PoolManager` class or the generic request interface, ensuring the documentation remains accurate for both urllib3 v1 and v2 users.

This addresses the documentation aspect of PR #1290.
