azure-sdk-for-net: [BUG] No distributed traces for Azure.Storage.Blobs and Azure.Messaging.ServiceBus when running in Azure Functions

Describe the bug

I can find some traces for the following SDKs:

• Azure table (used by durable functions)
• Old cosmos SDK (3.19)

However I am heavy user of Azure.Storage.Blobs (12.8.4) but my code is running in Azure Function v3 so I guess the old SDK is in the dependency tree somewhere.

Expected behavior

I expect to see information about my blob traffic.

Actual behavior (include Exception or Stack Trace)

no dependency metrics for storage blobs

To Reproduce

Run the code.
