ci: build i18n-utils before unit tests

The create package's tests spawn bin/run.js, which in dev mode loads
src/index.ts via tsx and imports @modern-js/i18n-utils — whose dist is
not present in the ut jobs (they only build build:required packages
before running rstest). Add @modern-js/i18n-utils to build:required;
verified by reproducing the CI failure locally (rm i18n-utils dist →
same ERR_MODULE_NOT_FOUND → build:required → 6/6 pass).
