Add a variables like OPENAI_BASE_URL and OPENAI_MODEL to use other AI model providers

[gmag11]

🔖 Feature description

There are many other AI providers who offer GPT4o models with OpenAI compatible API. This would allow to use even other models even local ones.

🎤 Why is this feature needed ?

Using alternate providers and or models, opening the possibility to use OpenAI compatible endpoints. Some examples:

• OpenRouter
• LiteLLM
• OpenWebUI
• Ollama

✌️ How do you aim to achieve this?

Just adding the proper parameters to const openai in libraries/nestjs-libraries/src/openai/openai.service.ts would allow this
