Revise content of CONTAINERS module

[tomDag25]

Module to maintain

Website: Brainhack Containers module
Code: Jupyter Notebook

Work to be done

I took the module this year and the code provided in the jupyter notebook is not working if you don't have a linux distribution. I'm working on a:
Darwin MacBook-Pro-3.local 23.3.0 Darwin Kernel Version 23.3.0: Wed Dec 20 21:28:58 PST 2023; root:xnu-10002.81.5~7/RELEASE_X86_64 x86_64

And when I run the code I get:

(base) thomasdagonneau@MacBook-Pro-3 ~ % wget bit.ly/fish-container -O fish.tar mkdir -p container-root && (cd container-root && tar xf ../fish.tar)

I think it doesn't work because I'm not with a linux user but instead a x86_64 mac user.
I couldn't test it but I think the issue would probably apply on a windows OS.
