chore: add JS only higher order functions lab to frontend cert

[jdwilkin4]

We need a lab for campers to practice working with higher order functions like map, filter, etc. This will be JS only. Not HTML or CSS or DOM manipulation.

Here is the workshop they will do before this https://github.com/freeCodeCamp/CurriculumExpansion/blob/main/frontend-cert/js-projects/library-manager/script.js

They will also know all of the fundamentals (strings, functions, objects, arrays, etc)

This doesn't need to cover everything in the workshop, just pick a couple of things like map or filter.

Acceptance criteria

• [ ] create a new folder of the project in the frontend-cert/js-projects directory
• [ ] add your completed project in that new folder
• [ ] create a markdown file for your proposed user stories. You should call it user-stories.md and place it in your new project folder
