Python: Bug: Python - Semantic Kernel Realtime isn't supporting the GA versions of Azure OpenAI realtime models

[nourshaker-msft]

Describe the bug
When attempting to use any of the new GA models in Azure OpenAI for Semantic Kernel Realtime, you're faced with an error

To Reproduce
Steps to reproduce the behavior:

1. Deploy a GA model from Azure OpenAI
2. give any name that's not in this list ('gpt-4o-realtime-preview', 'gpt-4o-realtime-preview-2024-10-01', 'gpt-4o-realtime-preview-2024-12-17', 'gpt-4o-realtime-preview-2025-06-03', 'gpt-4o-mini-realtime-preview' or 'gpt-4o-mini-realtime-preview-2024-12-17')
3. Run a code sample from https://learn.microsoft.com/en-us/semantic-kernel/concepts/ai-services/realtime?pivots=programming-language-python or https://github.com/Azure-Samples/AI-Gateway/blob/main/labs/realtime-mcp-agents/realtime-mcp-agents.ipynb
4. See error

session.model Input should be 'gpt-4o-realtime-preview', 'gpt-4o-realtime-preview-2024-10-01', 'gpt-4o-realtime-preview-2024-12-17', 'gpt-4o-realtime-preview-2025-06-03', 'gpt-4o-mini-realtime-preview' or 'gpt-4o-mini-realtime-preview-2024-12-17' [type=literal_error, input_value='gpt-realtime', input_type=str] For further information visit https://errors.pydantic.dev/2.11/v/literal_error

Expected behavior
It should work as expected as it used to whilst we still had preview models

Additional context
Workaround, at deployment time, name the GA model as gpt-4o-realtime-preview
