Embedding and Reranking models

It would help if there was a node for:

Jina AI LLM Models

My use case:

I want to use RAG based on Jina AI Embed and Rerank models

Any resources to support this?

There is a langchain community package in JS for Jina Embedding, but not the Rerank model.
There are both Embedding and Rerank packages for the lanchain community (Python version).

Are you willing to work on this?
