UnsupportedOperationException: null on GcsBackupStore.closeAsync

[korthout]

Describe the bug

An error was reported on development-worker-1:

message: "Failed to install partition 1"
  java.lang.UnsupportedOperationException: null
  io.camunda.zeebe.backup.gcs.GcsBackupStore.closeAsync
  io.camunda.zeebe.broker.system.partitions.impl.steps.BackupStoreTransitionStep.prepareTransition
  io.camunda.zeebe.broker.system.partitions.impl.PartitionTransitionProcess.lambda$proceedWithPrepare

I don't think this is an actual bug, but I wanted to report it to make sure as we are getting close to releasing 8.2 and this happened on 8.2.0-alpha5.

This happened around the same time as #12123 and is likely related.

To Reproduce

Unsure, it was reported by google error reporting.
