docs: clarify tutorials usage

[gcroci2]

I added a disclaimer in the tutorials' readme to make user that users know that they are not supposed to run the notebooks' code into python interactive shell.

Good addition. This clarifies that users should use the system we provide.
I do think we can be less explicit about what goes wrong if they don't (as per my suggestion below).

Also, should this PR point to dev instead of main? or is that not needed if it's just docs changes? It looks like it was branched off of dev, but now points to main.

I accepted your suggestion and I removed the section's title (thinking about it the note is enough)

Indeed, moved to dev :)
