Adding initialVisibilityDelay option to Azure Storage Queue binding

[willvelida]

Description

This PR implements the initialVisibilityDelay option for Azure Queue Storage Binding. This feature allows setting a delay before a message becomes visible in the queue after being added, which is a functionality available in the Azure Storage Queue service.

The implementation includes:

1. Adding the InitialVisibilityDelay field to the storageQueuesMetadata struct with appropriate mapstructure tags
2. Modifying the QueueHelper interface to include the initialVisibilityDelay parameter in the Write method
3. Updating the AzureQueueHelper.Write implementation to use the initialVisibilityDelay parameter when calling EnqueueMessage
4. Adding logic in the AzureStorageQueues.Invoke method to extract initialVisibilityDelay from request metadata
5. Adding documentation in metadata.yaml for the new option
6. Creating tests to verify the functionality:
   • Added a specific unit test TestWriteWithInitialVisibilityDelay that verifies the initialVisibilityDelay parameter is correctly passed from the request metadata to the Write method
   • Updated the mock helper to support the new initialVisibilityDelay parameter
   • Modified existing tests to accommodate the new parameter, ensuring backward compatibility
   • Verified that the functionality works properly by asserting that the value passed to EnqueueMessage matches the expected value

If this value is passed as a parameter but isn't expected to change dynamically, I suggest making it a struct property in the types that implement this interface.

After setting the default value to 0, I was thinking that if we keep it as a parameter, consumers can configure it on a per-message basis and it keep some consistency with the ttl parameter. I'm also think that using a struct here could introduce race conditions with the binding.
