Lesson assets should be served by the CDN

[ojeytonwilliams]

Describe the bug
We host various curriculum assets on S3.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures-v8/learn-basic-string-and-array-methods-by-building-a-music-player/step-5
2. See links to https://s3.amazonaws.com/org.freecodecamp.mp3-player-project

Expected behavior
They should be hosted on https://cdn.freecodecamp.org/ since S3 is designed to store content, not serve it. By using the CDN the lesson assets can be cached near the learner, resulting in better performance.

Steps to fix

• search for amazonaws.com in the curriculum/challenges/english folder to find the assets
• add the assets to https://github.com/freeCodeCamp/cdn
• update the lessons to use the new assets
• delete the buckets

There's few other files with amazonaws links outside of music player project:

• 01-responsive-web-design/responsive-web-design-principles/use-a-retina-image-for-higher-resolution-displays.md
• 01-responsive-web-design/responsive-web-design-principles/make-an-image-responsive.md
• 01-responsive-web-design/css-flexbox/add-flex-superpowers-to-the-tweet-embed.md
• 03-front-end-development-libraries/front-end-development-libraries-projects/build-a-drum-machine.md
• 04-data-visualization/json-apis-and-ajax/convert-json-data-to-html.md
• 10-coding-interview-prep/take-home-projects/build-a-simon-game.md

A quick note about the music player.

A couple of years back, I had added some of the songs to the cdn.
But with the revisions to the project, it looks like aws was used instead for the live site.
So, when we do create a PR to move the rest of the songs to the cdn repo, there is already a folder for it here
https://github.com/freeCodeCamp/cdn/tree/main/build/curriculum/js-music-player

Hey @ojeytonwilliams !

The last PR for replacing the links in the english curriculum has been merged to main.
So on the next website deployment, all links should be updated in production.

I guess we need to wait for the translations to be updated too.
But I am not sure how that works.

But the english files are set 👍

Awesome, thanks @jdwilkin4!

The translations are already live, so it just remains to delete the buckets. I'll take care of that and close the issue.
