Brayden Zhong e4515f308f community: update RankLLM integration and fix LangChain deprecation (#29931)
# Community: update RankLLM integration and fix LangChain deprecation

- [x] **Description:**  
- Removed `ModelType` enum (`VICUNA`, `ZEPHYR`, `GPT`) to align with
RankLLM's latest implementation.
- Updated `chain({query})` to `chain.invoke({query})` to resolve
LangChain 0.1.0 deprecation warnings from
https://github.com/langchain-ai/langchain/pull/29840.

- [x] **Dependencies:** No new dependencies added.  

- [x] **Tests and Docs:**  
- Updated RankLLM documentation
(`docs/docs/integrations/document_transformers/rankllm-reranker.ipynb`).
  - Fixed LangChain usage in related code examples.  

- [x] **Lint and Test:**  
- Ran `make format`, `make lint`, and verified functionality after
updates.
  - No breaking changes introduced.  

```
Additional guidelines:
- Make sure optional dependencies are imported within a function.
- Please do not add dependencies to pyproject.toml files (even optional ones) unless they are required for unit tests.
- Most PRs should not touch more than one package.
- Changes should be backwards compatible.
- If you are adding something to community, do not re-import it in langchain.

If no one reviews your PR within a few days, please @-mention one of baskaryan, efriis, eyurtsev, ccurme, vbarda, hwchase17.
