[New article]: Use an Azure SDK library with a sovereign cloud

### Proposed topic or title

Sovereign cloud usage

### Location in table of contents.

To be added under the "Library method types" ToC link at https://learn.microsoft.com/dotnet/azure/sdk/azure-sdk-for-dotnet

### Reason for the article

The Azure SDK client libraries default to using the Azure Public Cloud. If you need to use a sovereign cloud instead, good luck. The documentation is sparse.
