Describe the bug
We are using below code to create hub with storage account but issue in hub creation. Hub creates with storage account access as Credential-based access instead Identity-based access
`from azure.ai.ml import MLClient
from azure.ai.ml.entities import (
Hub,
Project,
ApiKeyConfiguration,
AzureAISearchConnection,
AzureOpenAIConnection,
IdentityConfiguration,
)
from azure.keyvault.secrets import SecretClient
from azure.identity import DefaultAzureCredential
from azure.storage.blob import BlobServiceClient
from azure.mgmt.storage import StorageManagementClient
from azure.mgmt.storage.models import (
StorageAccountCreateParameters,
Sku,
Kind,
)

key_vault_name = "kv_to-be-replaced"
subscription_id = "subscription_to-be-replaced"
resource_group_name = "rg_to-be-replaced"
aihub_name = "ai_hub_" + "solutionname_to-be-replaced"
project_name = "ai_project_" + "solutionname_to-be-replaced"
deployment_name = "draftsinference-" + "solutionname_to-be-replaced"
solutionLocation = "solutionlocation_to-be-replaced"
storage_account_name = "storageaihub" + "solutionname_to-be-replaced"

credential = DefaultAzureCredential()
ml_client = MLClient(
workspace_name=aihub_name,
resource_group_name=resource_group_name,
subscription_id=subscription_id,
credential=credential,
)

Create a Storage Management client

storage_client = StorageManagementClient(credential, subscription_id)

Create the storage account if it doesn't exist

storage_account_params = StorageAccountCreateParameters(
sku=Sku(name="Standard_LRS"),
kind=Kind.STORAGE_V2,
location=solutionLocation,
identity={"type": "SystemAssigned"},
allow_shared_key_access=False,
)
storage_account = storage_client.storage_accounts.begin_create(
resource_group_name, storage_account_name, storage_account_params
).result()

Define the Hub with Managed Identity

my_hub = Hub(
name=aihub_name,
location=solutionLocation,
display_name=aihub_name,
storage_account=storage_account.id,
identity=IdentityConfiguration(type="SystemAssigned"),
)

Create the Hub

created_hub = ml_client.workspaces.begin_create(
my_hub, update_dependent_resources=True
).result()

Construct the project

my_project = Project(
name=project_name,
location=solutionLocation,
display_name=project_name,
hub_id=created_hub.id,
)

created_project = ml_client.workspaces.begin_create(workspace=my_project).result()`

To Reproduce
Steps to reproduce the behavior:

1. Use the above code to create Hub and storage The hub creates with credential based access

Expected behavior
It should create AI hub and storage account based on identity based access.
