Data 8 Tech Stack Page is very verbose

[alexnakagawa]

In hindsight, the Data 8 Tech Stack page (https://ucbds-infra.github.io/ds-course-infra-guide/jupyterhub/data8.html) is a huge wall of text. Since it's listing quite a few technologies, we may want to consider formatting it differently (such as a table) to get the point across better. At the very least, use some highlighting or bolding.
