community: Deprecate Amazon Neptune resources in langchain-community (#29191) Related: https://github.com/langchain-ai/langchain-aws/pull/322 The legacy `NeptuneOpenCypherQAChain` and `NeptuneSparqlQAChain` classes are being replaced by the new LCEL format chains `create_neptune_opencypher_qa_chain` and `create_neptune_sparql_qa_chain`, respectively, in the `langchain_aws` package. This PR adds deprecation warnings to all Neptune classes and functions that have been migrated to `langchain_aws`. All relevant documentation has also been updated to replace `langchain_community` usage with the new `langchain_aws` implementations. --------- Co-authored-by: Chester Curme <chester.curme@gmail.com>
