      Context

      Our existing retriever in langchain does not use the new $rankFusion built in operator.
      See docs: https://www.mongodb.com/docs/atlas/atlas-vector-search/hybrid-search/
      There is also a blog post and such.

      Definition of done

      What must be done to consider the task complete?

      Implement existing retriever using this new operator, prove that the numbers remain the same, and merge to langchain-mongodb.
