[Feature Request]: Support for langchain 1.x for langchain-bridge #20134
Description
Feature Description
The file https://github.com/run-llama/llama_index/blob/main/llama-index-core/llama_index/core/bridge/langchain.py appears to be compatible with LangChain 0.3.x, as far as I can tell.
Is it possible to make it compatible with langchain 1.x?
Reason
Currently, an old langchain version must be installed in order to use the bridge.
Value of Feature
Version conflicts are a pain in python, and it would help to reduce the conflicts with newer langchain versions.
