`notebooks/course/en/chapter12 /grpo_finetune.ipynb` Not Found

[Mactor2018]

I was learning the tutorial of Practical Exercise: Fine-tune a model with GRPO on Huggingface, and when I clicked the button " open in Colab," Colab told me that "Notebook not found." After checking in this repo, I found it was moved to notebooks/course/en/chapter**13** /grpo_finetune.ipynb, so I suggest you correct the path on Colab. Thanks!
