More Py3.12 fixes (#1900)

* Increase size of buffered data in transport tests

It appears that py3.12's gzip implementation is more efficient, and as a
result the tests against `api_request_size` were failing. This change
should still work against older versions, as I also increased the
"don't send" test case.

* Disable kafka-python for Python 3.12
