feat(adapters): add langchain tool adapter

[Tomas2D]

Create a beeai-framework/adapters/lanchain/tool.py adapter for wrapping LangChain tools into the framework's native tool.

Usage TS: https://github.com/i-am-bee/bee-agent-framework/blob/main/typescript/examples/tools/langchain.ts

langchain_tool = LangChainWikipediaTool()
tool = new LangChainTool(langchain_tool);
