Community: Update and fix ZenGuardTool docs and add ZenguardTool to init files (#23415)

Thank you for contributing to LangChain!

- [x] **PR title**: "community: update docs and add tool to init.py"

- [x] **PR message**: 
- **Description:** Fixed some errors and comments in the docs and added
our ZenGuardTool and additional classes to init.py for easy access when
importing
- **Question:** when will you update the langchain-community package in
pypi to make our tool available?


- [x] **Lint and test**: Run `make format`, `make lint` and `make test`
from the root of the package(s) you've modified. See contribution
guidelines for more: https://python.langchain.com/docs/contributing/

Thank you for review!
