refactor: unify all language versions to use index.md instead of intro.md

- Rename stage-2/intro.md to stage-2/index.md for all languages
- Rename stage-3/intro.md to stage-3/index.md for all languages
- Rename appendix/intro.md to appendix/index.md for all languages
- Update config.mjs navigation links to use /stage-2/ and /stage-3/ instead of /stage-2/intro and /stage-3/intro
- This follows VitePress best practice where index.md is the default page for a directory
