add Making a CHIP-8 emulator in Zig

[alvarorichard]

This is just a tutorial I found about creating a CHIP-8 emulator in Zig during some web research. I found it interesting to share, believing that it may help people interested in learning Zig or building something with this language. Additionally, since there are few Zig tutorials available, I hope this contributes to the project and assists others. It's important to note that this tutorial is not my own; I'm simply sharing it
