chore: add lab for weather app to review fetch API in frontend cert

[jdwilkin4]

The last JS section will be on asynchronous JavaScript. So we need a lab for campers to practice.

They will have done this workshop just before this lab https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures-v8/learn-fetch-and-promises-by-building-an-fcc-authors-page/step-29

Convert this take home weather app project into a lab https://www.freecodecamp.org/learn/coding-interview-prep/take-home-projects/show-the-local-weather

The original codepen was inspired by this project here https://codepen.io/joshbader/full/EjXgqr/

But we should create our own design for the demo project.

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
