Missing Server header from responses from some Azure Storage Queue accounts

### Bug Title

Missing Server header from responses from some Azure Storage Queue accounts

### Crate Name

azure_storage_queues

### Crate Version

0.21.0

### Description

Hi,

I've been using the legacy version of the azure_storage_queue crate and it failed to communicate with queues in a recently created storage account because it is missing the "Server" HTTP header that the library expects. Example of curl commands to reproduce in the reproduction section.

This seems like a bug in upstream Azure? The Server header is present in a bunch of Azure examples from the Azure Storage Queue REST documentation and the legacy library depends on it. I have not tried with 0.2.0 yet.
