Checklist

• [X] I added a very descriptive title to this issue.
• [X] I included a link to the documentation page I am referring to (if applicable).

Issue with current documentation:

https://python.langchain.com/v0.2/docs/how_to/custom_tools/ Using any of the code for the tools on this page leads to a TypeError. For example using the code from https://python.langchain.com/v0.2/docs/how_to/custom_tools/#tool-decorator will give a TypeError: args_schema must be a subclass of pydantic BaseModel. Got: <class 'pydantic.v1.main.multiplySchema'> error. The same will happen for the rest of the functions that have been defined in the documentation.

Hi updating langchain to 0.2.1.0 did not fix the issue but upgrading to python3.11 did

@owaist37 include the output of: python -m langchain_core.sys_info. We're missing the langchain-core version from your report.
