Bug: Broken Links to Blog Posts

[stygian-ash]

The live version of the website at ml5js.org contains broken links to archived blog posts. Blog posts listed on the index page such as "Introducing ml5.js Code of Conduct" link to /(link), leading to a 404.

This seems to be because blog posts are being treated the same as featured projects

Line 16 in f9396de

const projects = data.allMarkdownRemark.nodes

ml5-website-v02-gatsby/src/pages/index.js

Lines 122 to 124 in f9396de

	{projects.map((project) => (
	<ProjectBox

but lack a valid externalLink property

Line 8 in f9396de

externalLink: (link)

which featured projects have.
