feat(dev): On Apple arm64 install hosted confluent-kafka wheel (#29013)

There's no `arm64` wheel for confluent-kafka, thus, it needs to be built as part of the `pip install` step. Instead of waiting for official support, I've uploaded the wheel I produced into a GC bucket.

Alternatively, we would automate a convoluted build process (see [issue][upstream] for details).

Fixes #28429.

[upstream]: confluentinc/confluent-kafka-python#1190
