integrating new tutorials into the master branch

[edublancas]

the tutorials branch contains revamped tutorials. More information on why we created these new tutorials is in: https://github.com/ploomber/soopervisor/issues/109 - essentially, the current ones do not contain the output of each command, which makes them hard to follow

a few things:

• tutorials require some extra files to work. currently, the tutorials assume the files exist locally, but we should replace them with curl commands. see this: https://ploomber.io/blog/ds-platform-part-i/ for an example of what we're looking for
• ignore the argo-pykernel.ipynb file, since we'll be using the argo.ipynb version (the latter uses the bash kernel)
• the bash kernel gets a little crazy when the commands output a lot of text, so you might wanna redirect the output to a file
• the tutorials should replace the old ones (e.g., use the argo.ipynb and delete the existing one
