Thank you for contributing to LangChain! - [x] **PR title**: "package: description" - Where "package" is whichever of langchain, core, etc. is being modified.

It lives in `docs/docs/integrations` directory. - [x] **Lint and test**: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified.
