Missing Starlette urllib3 pin

Medium Severity

The new FastAPI deps comment says Starlette below 0.21 needs urllib3&lt;2 because _MockOriginalResponse lacks close(), and FastAPI now pins that. The Starlette suite still tests 0.20.4 and installs requests without the same pin, so those envs can still resolve urllib3 2.x and hit the TestClient failure this change is meant to avoid.
