Feature request

I am encountering an issue when trying to use the mistralai/Mistral-Nemo-Instruct-2407 model with the ChatMistralAI class. Other Mistral models are working fine, but it seems this specific model is not supported or there is a configuration issue. Could you add compatibility for this model in an upcoming update?

The model works with the HuggingFaceInference class, but managing streaming and toolkit features is more complex in that case. Could you add compatibility for this model in an upcoming update to make it easier to handle streaming and toolkit functionalities?

version @langchain/mistralai: 0.1.0
model: mistralai/Mistral-Nemo-Instruct-2407

Error: MistralAPIError: HTTP error! status: 400 Response:
{"object":"error","message":"Invalid model: mistralai/Mistral-Nemo-Instruct-2407","type":"invalid_model","param":null,"code":"1500"}

Motivation

I am working on a solo project, and based on the available statistics, the Mistral Nemo model is highly interesting due to its performance and open-source nature. Its ability to handle context efficiently while maintaining a lightweight system is a key factor for choosing this model in my project.
