2024-08-08: GPT-4o-mini support

This release includes support for gpt-4o-mini for the chat completion requests. This support required an update to the token counting package. See instructions for switching here:
https://github.com/Azure-Samples/azure-search-openai-demo/blob/main/docs/deploy_features.md#using-gpt-4
Unfortunately, gpt-4o-mini is only in eastus, so you may need to change the location of your OpenAI resource. You can change that in .azure/ENV-NAME/config.json

What's Changed

• Upgrade openai, openai-messages-token-helper, for gpt-4o-mini support by @dependabot in #1893
