Add script to generate article template

[houzyk]

• Add article template
• Automatically add details such as github name, username and article title into template
• Offer a CLI
• Probably run on node

[houzyk]

Specs:

• Run npm run generate-article
• Prompts for github username
• Checks if username is valid
• if not valid, prompts again
• if valid, get ghub name & prompt for article title in kebab case
• title checks -> kebab case, less than 15 words
• if checks do not pass -> prompt again
• if ok, generate the following:

1. a folder in ./public/images called <article-name>. Folder should contain a default cover.webp.

2. a template article in ./content/articles/<article-name>

Template should have a frontmatter as follows:

external: false
title: "<article-title-normal-case>"
description: "Please add your description here. This should match the below"
author: "<github name>"
authorUrl: "https://github.com/<github-username>"
ogImagePath: "/images/<article-title>cover.webp"
date: 2000-01-01

Template should have a cover and intro as follows:

![<article-name-normal-case>](/images/<article-title>/cover.webp)

>   Please add your description here. This should match the above

3. {name: "git hub name", url: "<github url + username>"} to authors key in ./content/people.json

We should then have a default template for the cover.webp and any article (in .md)
