docs: fix broken links in translated READMEs

Fixed broken links to non-existent quick-start-practices.md:
- Changed to point to basic-examples.md instead
- Fixes 3 broken links reported in README quality check
- Affects: README-ja.md, README-zh.md, README-kr.md

Note: Translated READMEs have fewer headers (30) than main
README (58), indicating incomplete translations. This is a
known documentation synchronization issue.
