Ebazhanov/linkedin-skill-assessments-quizzes ? reverse-engineered prompt

Build me a simple study site for LinkedIn skill assessment quizzes, using the quiz content in this repo.

I want it to feel like a clean reference library where someone can pick a topic like JavaScript, Python, React, AWS, Git, HTML, or Machine Learning, open the questions, and see the answers and any short explanations or source links. Make it easy to browse by category, search for a skill, and jump between the English version and translated versions where they exist.

Please also include a homepage that explains these assessments are no longer on LinkedIn, but the material is still useful for practice. Add a section for contributing new questions or fixes, and make the layout easy to read on desktop and mobile. If you need to check current docs or best practices for generating the site, look them up online first.
