Add syntax highlighting to the code snippets on the website

[thibaudcolas]

https://ouluwebdev.github.io/hello-hacktoberfest/ displays all Hello, World! snippets, but it doesn't have syntax highlighting. We need to add that!

It should:

• Automatically detect what language a snippet is written in (based on the code and-or the file extension) (basically what https://github.com/github/linguist does, but in JS)
• Use a tool like https://prismjs.com/ or https://highlightjs.org/ to do the actual highlighting
• Fall back to "no highlighting" if the language cannot be determined

I can take a swing at this. Can you assign the task to me?

[thibaudcolas]

@kwaimind sure! Let me know if I can help.

[thibaudcolas]

Actually GitHub only allows to assign people who have contributed at least once. But consider it yours!

Added prism but having an issue getting the right syntax to show. Working on it.
