What

The binary packaged with Platform should have the update command disabled, because each release of Confluent Platform has a fixed CLI version. Even if customers do want to upgrade it, they should do so through package managers.

We upload archives, but not binaries, with updates disabled. This PR corrects a bug that tries to pull the binary by instead pulling the archive and extracting the binary from it.

Test & Review

I tested the updated for loop locally on my machine.
