Updated dependencies, generated API.

Description

• This should fix some of the open CVEs. I am not 100% that setting newer min versions for requests, urllib3 and certifi is right, so please lmk if you think it's not.
• Ran the generator and added new API namespaces.
• Locked setuptools, newer versions fail in nox ... tests with Unknown distribution option: 'test_suite'..
• Removed flaky 2.0 from tests.
• Reduce the mad test matrix of every minor release that hasn't yielded a bug in forever.

• 'urllib3>=1.26.19,!=2.2.0,<3 ; python_version >= "3.10"', here 2.2.1 should also be removed as per affected versions here https://github.com/urllib3/urllib3/security/advisories/GHSA-34jh-p97f-mpxf
