2024-06-03b: Speech output with browser

You can now optionally enable speech output using the Browser SDKs, as opposed to using the Azure Speech SDK. The speech output is generally not as fluid, but it's entirely free, so it's a great zero-cost option to increase accessibility. See docs at:
https://github.com/Azure-Samples/azure-search-openai-demo/blob/main/docs/deploy_features.md#speech-output

We've also added documentation about a Python-based load balancer for OpenAI instances. See:
