Issue in the code provided in unit1 tutorial

[human-coder-mj]

The code given in the agents-course/units/en/unit1
/tutorial.mdx is different from the one given in the repository.

• The code in the tutorial is importing the tools from smolagents library.

from smolagents import CodeAgent, DuckDuckGoSearchTool, FinalAnswerTool, InferenceClientModel, load_tool, tool
import datetime
import requests
import pytz
import yaml

• The code in the repository maintains the tools in a directory and are imported from there.
