### Description

<!-- Describe your changes, the overall approach, the underlying design.
These notes will help understanding how your code works. Thanks! -->
When importing anything from semantic_kernel.connectors.ai.openai it
already needs websocket and aiortc, so moved those.
Kept the extra for now, while we build a more sustainable fix.
