feat: remote ramalama provider implementation

Implement remote ramalama provider using AsyncOpenAI as the client since ramalama doesn't have its own Async library.
Ramalama is similar to ollama, as it is a lightweight local inference server. However, it runs by default in a containerized mode.

RAMALAMA_URL is http://localhost:8080 by default
