Missing `name` in `ResponseFunctionCallArgumentsDoneEvent` for realtime

[arkadiy-telegin]

De facto API returns name of the function we want to call under key name, but the API spec and hence the SDK libs are missing it.

Example as returned by the API:

{
  'type': 'response.function_call_arguments.done',
  'event_id': 'event_xxx',
  'response_id': 'resp_xxx',
  'item_id': 'item_xxx',
  'output_index': 0,
  'call_id': 'call_xxx',
  'name': 'Done',
  'arguments': '{}'
}
