[BUG] Connections broken in flows and connections dialogs

[fausttiger007]

Describe the bug Trying to show Connections in Prompt Flow via old Connections menu... gives Failed to get secret for connection 'Default_AzureOpenAI'. Service invocation failed! Request: POST management.azure.com/subscriptions/xxxxxxxx/resourceGroups/BIDSMachineLearning-dev-rg/providers/Microsoft.CognitiveServices/accounts/meuw-xxx-xxxx/listKeys Status Code: 403 Forbidden Reason Phrase: Forbidden Response Body: S2S invocation to arm failed when calling: https://management.azure.com/subscriptions/xxxxxxxx/resourceGroups/BIDSMachineLearning-dev-rg/providers/Microsoft.CognitiveServices/accounts/meuw-xxxxxxxx/listKeys?api-version=2023-10-01-preview

Separate "new preview" Connections Workspace dialog lists connections, but Prompt Flows can not see connections.

Separate PromptFlow run in SDK has similar issue.

Prompt Flow in AI Studio appears to work.

Did the API Version change, and prompt flows themselves need to be updated somehow? https://management.azure.com/subscriptions/xxxxxxxx/resourceGroups/BIDSMachineLearning-dev-rg/providers/Microsoft.CognitiveServices/accounts/meuw-xxxxxxxx/listKeys?api-version=2023-10-01-preview
