Add Improved Link to tutorial - Build Snake using only Javascript, HTML & CSS

The link provided before directed to tutorial with missing parts and code snippets. So I updated it.

Description

The previous link directed to freecodecamp website's tutorial which might have been migrated from the medium tutorial site. The tutorial on freecodecamp is missing lots of code snippets along with misplaced spacing on the site. Due to the missing parts it gets very hard to follow the tutorial, rendering it to be even unuseable.

Motivation and Context

• I wanted to improve the link so that the problem I faced won't bother future devs who check out the link and judges the tutorial based on the previous link.
• It solves the issue of partially readable tutorial to a readable tutorial which is actually fun to follow.

How Has This Been Tested?

• I tested the link and it redirects to the original tutorial on medium
