Freecodecamp: docs: add cypress tests documentaton to contribution guides

[luqven]

Is your feature request related to a problem? Please describe.

Had trouble getting up to speed with Cypress since there's currently no documentation on for how it's implemented in the code base.

Describe the solution you'd like

I suggest we create a documentation page for Cypress that outlines how to:

• 1) run the tests locally and
• 2) create end-to-end tests using Cypress whenever adding to the code base.

This section could potentially be under the "Open a pull request" section of "Code Contribution Guides".

Describe alternatives you've considered

A a link to the docs already on cypress.io could be added to the introduction, but in my opinion this would probably be insufficient.

Additional context

• the PR where I created a Cypress test: #38806
• Cypress.io docs

_ps: I'd love to give a PR for this a stab if it's decided it's needed._

Sounds good to me. I think it would be best to focus on freeCodeCamp specific issues, rather than diving too deep into how Cypress tests work. The Cypress docs cover that, after all.

Great, thanks! Since you've just looked at this, that makes perfect sense.

Picking this up again. Sorry the the multi-month delay 😬, life took some crazy turns.

Hey @luqven no apology necessary, it's always nice to see someone come back.
