* added: Neo4j database connectivity, Neo4j credentials, supports the usage of the GraphCypherQaChain node and modifies the FewShotPromptTemplate node to handle variables from the prefix field.

* Merge branch 'main' of github.com:FlowiseAI/Flowise into feature/graphragsupport

* revert pnpm-lock.yaml

* add: neo4j package

* Refactor GraphCypherQAChain: Update version to 1.0, remove memory input, and enhance prompt handling

- Changed version from 2.0 to 1.0.
- Removed the 'Memory' input parameter from the GraphCypherQAChain.
- Made 'cypherPrompt' optional and improved error handling for prompt validation.
- Updated the 'init' and 'run' methods to streamline input processing and response handling.
- Enhanced streaming response logic based on the 'returnDirect' flag.

* Refactor GraphCypherQAChain: Simplify imports and update init method signature

- Consolidated import statements for better readability.
- Removed the 'input' and 'options' parameters from the 'init' method, streamlining its signature to only accept 'nodeData'.

* add output, format final response, fix optional inputs
