Link not working to sample dataset

Page Not Found: A small dataset, containing 5 T1w and T2w images, is available [here](https://osf.io/h73cm/) and is used as example for preprocessing.

Sorry I don't remember what dataset it was. @benjamindeleener do you?

Alternatively, we can point to another small dataset. Eg, i'm thinking maybe a subset of the spine-generic dataset, or the 3 subjects from the SCT course (https://github.com/spinalcordtoolbox/sct_tutorial_data/tree/master/multi_subject/data) (although it has MT images which we don't need here)

I think it was a sub-sample of the PAM50 dataset, which was probably removed from OSF. Pointing to another dataset would be a good solution. It would be good if it has large coverage.

We use the Dog dataset and the Pediatric dataset for testing. We could perhaps use a subset of these datasets or use the a subset of the spine-generic dataset as mentioned above.
