[BUG]

### API Spec link

https://github.com/Azure/azure-rest-api-specs/blob/main/specification/cognitiveservices/data-plane/AzureOpenAI/inference

### API Spec version

any

### Describe the bug

I don't see realtime feature in any of the specification files for Azure Open AI, which are available in the OpenAI specification see: https://github.com/openai/openai-openapi/blob/acea67a5045a6873c6eb2573a6be0e0a7b092ec6/openapi.yaml#L7113

Models with this capability are available in AOAI such as gpt-4o-realtime-preview

### Expected behavior

realtime would be in the spec file

### Actual behavior

realtime is not in the spec file

### Reproduction Steps

If we Import this Spec file into Azure API Manager we can't use the realtime feature.

### Environment

_No response_

Start in the AzureOpenAI inference specification directory linked in the issue and compare its available operations with openapi.yaml around line 7113 in the referenced OpenAI specification. Verify how the specification is imported into Azure API Management, then confirm that the realtime capability appears in the Azure spec and can be used after import.
