Fill about page

**Is your feature request related to a problem? Please describe.**
The current about page is a template work-in-progress page:

> This page is a work in progress
Join CS Club to contribute to this page!

**Describe the solution you'd like**
The page should be filled with information about CS Club, such as location, history, what we do, pictures, etc.

The heads can be @'d on Discord if information is needed.

Start by locating the current about page and reviewing its work-in-progress template. Gather verified information from the CS Club heads, including location, history, activities, and suitable pictures, then replace the placeholder content; the page is done when it presents complete, accurate club information.
