Microsoft.Azure.WebJobs.Extensions.Storage.Queues 5.3.9

The Azure WebJobs Extensions Storage Queues 5.3.9 update fixes an issue where queue scale metrics incorrectly reported QueueLength=0 when messages were present but could not be decoded, preventing functions from scaling out. This update ensures scale metrics now read the queue using QueueMessageEncoding.None, avoiding decode failures in peek results while keeping message processing unaffected.
