Updated dependencies to fix breaking changes in requests (#1189)

* `requests` had critical security fixes that required updating minimum version
* This fix broke the `requests-unixsocket` dependency which used monkey-patching
* `requests-unixsocket` is abandoned, so switched to use the fork `requests-unixsocket2`
* Also updated `urllib3` dependency to be more flexible.
* Added support for Python 3.11 and 3.12
