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.
python/typeshed#10812

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

• botocore https://github.com/boto/botocore/blob/fcad88429eebfb3024be80e2700648c4a357ca16/setup.py#L28 - see chore(deps): update boto3 and botocore #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: elastic/elasticsearch-py#2216

But we're pinned back:

Line 16 in 56f0f6c

elasticsearch>=7.0.0,<7.11.0

Ah, this is because our Elasticsearch provider doesn't work with newer versions of elasticsearch: #10312

Might be time to replace our search backend...
