Host somewhere the tutorial/guided tour data file
### Feature description

Both the guided tour inside the UI and the tutorial on the website use a data file from the French OpenData website: https://www.data.gouv.fr/fr/datasets/r/d33eabc9-e2fd-4787-83e5-a5fcfb5af66d

Unfortunately, this file may not be available everywhere; we have reports from users that cannot access it while we can access it simultaneously.

We may want to host this file by ourself, or rely on a different data set.
