Added missing hyperlinks for Matplotlib, TensorFlow and Scikit-Learn in the Data Science docs page.

Type of Change

Description

I added 3 missing hyperlinks to the content/data-science/data-science.md file.

It was missing links for Matplotlib, Scikit-Learn and TensorFlow. I did it as a part of the Open Source project to practice contributing to the docs of Codecademy.

Issue Solved

The three hyperlinks have been added and they are functional. All 3 link to the official corresponding documents from codecademy.

It was a new issue, but I didn't create any because there were no instructions on how to do so.
