Add Azure OpenAI's ChatGPT Skill

[nakazax]

This PR adds an example skill for Azure OpenAI ChatGPT, as requested in issue #201. The example skill provides users with access to a sample conversation with the ChatGPT model on Azure OpenAI Service.

To demonstrate that the example skill is functional, I have created two demo videos that showcase the ChatdollKit integrated with Azure OpenAI ChatGPT and Azure TTS service. Please find the links to the demo videos below:

• Demo: ChatdollKit + Azure OpenAI ChatGPT + Azure TTS (ja-JP-NanamiNeural)
• Demo: ChatdollKit + Azure OpenAI ChatGPT + Azure TTS (ja-JP-AoiNeural)
