Subject: [PATCH] docs: Refactored AWS Lambda Tool to Use AgentExecutor instead
 of initialize agent  (#30267)

## Description:
- Removed deprecated `initialize_agent()` usage in AWS Lambda
integration.
- Replaced it with `AgentExecutor` for compatibility with LangChain
v0.3.
- Fixed documentation linting errors.

## Issue:
- No specific issue linked, but this resolves the use of deprecated
agent initialization.

## Dependencies:
- No new dependencies added.

## Request for Review:
- Please verify if the implementation is correct.
- If approved and merged, I will proceed with updating other related
files.
