[Bug]: Unknown Responses streaming event: response.rate_limits.updated

[ejellard]

Description

I can't reproduce this reliably as it is presumably related to rate-limits, but on the 0.18 branch we had a similar issue where the 'keepalive' event caused problems #732

We're getting the same style of error reports in our logs, 'Unknown Responses streaming event: response.rate_limits.updated'

Steps To Reproduce

Our code is broadly:

$client = OpenAI::client($secret);
$max_tool_rounds = 3;

for ($round = 0; $round <= $max_tool_rounds; $round++) {

    try {
        $stream = $client->responses()->createStreamed($current_params);

        foreach ($stream as $streamed_response) {
               // do stuff
        }

       // do stuff with tools via code similar to:
       //foreach ($response->output as $output) {
            // if ($output instanceof OutputFunctionToolCall) { }
     // }
   } catch (Exception|UnserializableResponse $e) {

   }
}

The error is throwing on the foreach ($stream as $streamed_response) line
