Add Connect Four game project link

Description

Added a Connect Four game project link to the README, built using HTML, CSS & JavaScript.

Motivation and Context

Connect Four is a great beginner-to-intermediate level project. It covers core JavaScript concepts like DOM manipulation, 2D arrays, game logic, and CSS Grid layout — making it a solid addition to the project-based learning list for anyone looking for a fun, visual challenge.

How Has This Been Tested?

Opened the live demo link and confirmed the project loads correctly.

Thanks for putting together a Connect Four write-up — the step-by-step breakdown of the game logic is genuinely nice work. However, this list aims to feature established tutorials with some track record, and since this page was created on your personal site just before opening the PR, it reads as self-promotion rather than a curated resource. If you publish it on a platform like dev.to or as a well-documented GitHub repo and it gains some traction, it could be a good fit in the future.

Thanks for the honest feedback, appreciate it. Fair point on the timing — I'll get it more traction on dev.to/as a standalone repo first and revisit this list down the line. Thanks for taking the time to look at it.
