* Adding Free Python, Datamining, Machine Learning Books (Corrected Categories)

There were a few issues with my original PR (https://github.com/EbookFoundation/free-programming-books/pull/4866/files), so I forked the main respository and added my updates based on @eshellman 's feedback.

Edits include:
- moving "Top 10 Machine Learning Algos..." by Mathews and Aasim --> Machine Learning
- moving "A Select Overview of Deep Learning" by Fan, Ma, and Zhong --> Machine Learning
- adding "Natural Langauge NLP with Python Tutorial" --> Python
- moving "The Ultimate Guide to 12 Dimensionality Reduction Techniques" by Sharma --> Datamining

Note: there was a linter error coming up in the previous PR that I wasn't sure about (https://github.com/EbookFoundation/free-programming-books/pull/4866)....so hopefully this is all set!

* Update free-programming-books.md
