Notebook 03_getting-started-with-transformers. - URLs invalid

Hello, thank you for this great resource. I wanted to check the tutorials, but the URLs do not work:

## Desc
Please note following URLs (both have same target) are not valid anymore.
- URL to Notion - [A tour through Hugging Face Hub](https://www.notion.so/Workshop-A-Tour-through-the-Hugging-Face-Hub-2098e4bae9ba4288857e85c87ff1c851):

- URL to Google Colab - [Build and Host Machine Learning Demos with Gradio & Hugging Face](https://colab.research.google.com/github.com/huggingface/education-toolkit/tree/main/02_ml-demos-with-gradio.ipynb):

## Solution?
This seems to be the material, but I am not sure
- I have found a similar video on Youtube:

```

```
- and a Google Colab Link in the above Youtube Description:
