feat(chatgpt-client.js, titleConvo.js, genAzureEndpoints.js): add support for Azure OpenAI API endpoint generation (#234)

This commit adds support for generating Azure OpenAI API endpoints in the
`chatgpt-client.js` and `titleConvo.js` files. The `genAzureEndpoint` function
in `genAzureEndpoints.js` generates the endpoint URL based on the provided
parameters. The `chatgpt-client.js` and `titleConvo.js` files now use this
function to generate the endpoint URL when the `AZURE_OPENAI_API_KEY` environment
variable is set.
