Cannot use Azure custom deployment due to fixed URL path

[lihenggui]

Description

I'm uncertain whether this is a bug or a feature request.

In this pull request (https://github.com/aallam/openai-kotlin/pull/102/files), it is stated that the library now supports custom deployments, including Azure. But we are currently unable to directly fetch data from Azure using this library due to a difference in the URL format.

According to the reference documentation (https://learn.microsoft.com/en-us/azure/cognitive-services/openai/reference), the correct URL format for retrieving embeddings from Azure is as follows: https://{your-resource-name}.openai.azure.com/openai/deployments/{deployment-id}/embeddings?api-version={api-version}.

Unfortunately, there is a hardcoded URL (v1/) in the code file that hinders the use of Azure services (https://github.com/aallam/openai-kotlin/blob/main/openai-client/src/commonMain/kotlin/com.aallam.openai.client/internal/api/EmbeddingsApi.kt#L31).

My suggestion is to consider relocating the URL path v1 to a configuration file, similar to the OpenAIHost, to allow users to easily modify it and ensure compatibility with Azure deployments.

Steps to Reproduce

1. Import the library to a project
2. Use Azure OpenAI deployment
3. Check the error message

HttpClient: RESPONSE: 404 Resource Not Found
METHOD: HttpMethod(value=POST)
FROM: https://{your-resource-name}.openai.azure.com/openai/deployments/{deployment-id}/v1/embeddings

Environment

• openai-kotlin version: 3.2.4
• Kotlin version: 1.8.10
• OS: MacOS ventrua
