Switch to kafka 3.5.2 (nv-morpheus#1612)

* The download for kafka 3.4.1 has been removed.
* This doesn't impact Morpheus itself, but impacts developers wishing to run Kafka integration tests. 

Closes nv-morpheus#1613

Note: The CI runner images have our previous version of kafka pre-downloaded, such that this change isn't actually tested in CI. I did test this locally in a fresh conda env.
