Export closures articles design assets from figma into repo and swap them out in the article instead

[ashwanth1109]

The "Demystifying JavaScript Closures" article was originally published by me in dev.to here: https://dev.to/ashwanth1109/demystifying-javascript-closures-4e3i

I copied the readme file over and it therefore still uses the image assets that were originally uploaded to dev.to
Need to export all the assets from figma into repo and deploy them to code-ninja s3 bucket and use them from there instead
