[Feature Request] add AI/ML API as provider

### 🥰 Feature Description

Hi!

I'm from the Integrations team over at [AI/ML API](https://aimlapi.com/)
Here are our docs: https://docs.aimlapi.com/

Your project looks dope, so we'd like to have a native integration with it. We already got integrations with Langflow, Agno, and AutoGPT - so our integrations team is pretty seasoned

Say you're interested, and we'll test the compatibility, update the code/docs to include us, create a PR and add a tutorial on using NextChat with AI/ML API to our docs

### 🧐 Proposed Solution

I'd like a pre-approve so that my team can get on it
