Describe the bug
When using the `live_request_queue.send_realtime(Blob=...) method, I get a deprecation warning that states:

DeprecationWarning: The `session.send` method is deprecated and will be removed in a future version (not before Q3 2025).
Please use one of the more specific methods: `send_client_content`, `send_realtime_input`, or `send_tool_response` instead.
  await self._gemini_session.send(input=input_blob)

To Reproduce
Steps to reproduce the behavior:

1. Set up a custom runner for live agent using WebSockets.
2. Call live_request_queue.send_realtime() to send images (video feed) or audio data.
3. See error
