Latest `types-requests` breaks deps build, surfaces urllib3 chain issue

[miketheman]

The latest types-requests package removes a dependency on types-urllib3, and the typeshed has completely removed urllib3 types from the shed, since they are available in 2.0.x series. https://github.com/python/typeshed/pull/10812

We are unable to upgrade to urllib3 yet, as some other tools pin to lower than 2.x

• [x] botocore https://github.com/boto/botocore/blob/fcad88429eebfb3024be80e2700648c4a357ca16/setup.py#L28 - see https://github.com/pypi/warehouse/pull/14747
• [ ] elasticsearch (we're pinned to 7.10.1 that requires <2, and even up to 7.17.9 https://github.com/elastic/elasticsearch-py/blob/deccbb732f17eee0937b7ec5980792849a2393d4/setup.py#L55 )

I'll pin urllib3 to <2 to resolve a lot of these chains until we can resolve the above.

Looks like elasticsearch==8.x.x supports urllib3<3: https://github.com/elastic/elasticsearch-py/issues/2216

But we're pinned back: https://github.com/pypi/warehouse/blob/56f0f6c719809564de44dbca18dff967d69930ac/requirements/main.in#L16

Ah, this is because our Elasticsearch provider doesn't work with newer versions of elasticsearch: https://github.com/pypi/warehouse/pull/10312

Might be time to replace our search backend...
