Creates readme-translations/*.md (Arabic, German, Spanish, French, Hindi, Indonesian, Italian, Japanese, Polish, Portuguese, Russian, Turkish, Chinese) and adds a language list, README Translations table, and a "Contributing Translations" subsection to README.md so contributors can find and update localized docs.
