Make compatible with requests 2.29.0 and urllib3 2.0 (#613)

* Make compatible with requests 2.29.0.

* This fix should also work with urllib3 2.0 according to urllib3 maintainer.

* Add changelog fragment.

* We still need the constraint for CI until Docker SDK for Python has a new release with a fix.

* Make modifications to response_class as small as possible.

* Revert "We still need the constraint for CI until Docker SDK for Python has a new release with a fix."

This reverts commit 698d544a1e08308e8bf8b4e56ab78c5079f9a17b.

* The pip coming with the ansible-core 2.11 alpine3 image seems to be too old.
