[UPDATE] What are LLMs section has unnecessary jupyter notebook information at the bottom.

[DecodersLord]

I feel line 216-220 are unnecessary under "What are LLMs?" section.

The bottom 3 lines talk about and starts with "To run this notebook" while the section doesn't talk about running any Jupyter notebook yet. The notebook links to "Dummy agent Library" section which is further down the course material, leading to misaligned information.

I feel like this 3 lines should be moved at the top of "Dummy agent Library" section or at the end of the module before that "Observe: Integrating Feedback to Reflect and Adapt" as an heads-up to what to come.

@sergiopaniego I see the last changes made by you under https://github.com/huggingface/agents-course/blame/0d02a7db0d312946cb0f12282d45f2225aaad474/units/en/unit1/what-are-llms.mdx#L216

Let me know if I can go ahead and fix this.
