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

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.
