docs(i18n): sync shields badges row to zh-TW / zh-CN / ja READMEs

The badges block (License MIT · Python 3.12+ · CI status · npx skills
install · agentskills.io compliant) was only on the English README in
the previous SEO pass. Mirror it onto the three translated READMEs so
readers landing on any language variant see the same signals. Badge
text + alt stays English (canonical for shields.io cross-linking); the
surrounding prose is the part that's localised.
