Make `machine-learning-with-python` work offline

[benoit74]

This is the overall goal of the milestone. It hence serves both as a basic requirement, instruction on what to look after during development and final checkup.

The goal of this milestone is to generate machine-learning-with-python ZIMs (one per supported languages). In FCC repo, all challenges markdown (in English) are stored under 11-machine-learning-with-python folder.

The command to create the EN ZIM is going to look like (title, description still have to be determined):

fcc2zim --course=tensorflow,how-neural-networks-work,machine-learning-with-python-projects --name tests_en_freecodecamp-11-machine-learning-with-python --zim-file tests_en_freecodecamp-11-machine-learning-with-python.zim --title "freeCodeCamp 11" --description "Machine Learning with Python" --language eng --overwrite

Final checklist

• Confirm list of audited spoken languages
• ZIM can be generated for all these spoken languages
• all challenges can be solved
• nothing is broken in the UI
• no external resources are significantly missing (sample project for an exercise, image, video, ...)
