"Page not found" error on post's link to source code

[aenyeart]

Context of Issue

Reading post titled Setting up Visual Studio Code for Web Development. Noticed a couple typos and tried to find and correct them here on GitHub. (Will create separate issue for typos.)

Problem

Clicking the link to source code at the bottom of the post to correct some typos leads to GH's 404 "Page not found" error.

Thoughts

• [ ] Check for deployment bug with Eleventy or CircleCI
• [ ] If some posts are intentionally not open source, I suggest removing the GH link from those specific posts.
