Typing stubs for urllib3

This is a PEP 561 type stub package providing type annotations for the `urllib3` library. It enables type-checking tools like Mypy, Pyright, and PyCharm to statically analyze code that uses `urllib3`. The package version is 1.26.25.14, and it is released as needed to align with updates from the `typeshed` repository. Users of `urllib3` version 2.0.0 or newer should *not* install this package, as `urllib3` now includes inline type annotations.
