skills(i18n): author the generated-bundle example through defineTranslationBundle (I18N-F-01 follow-up, I18N-G-05)

check:doc-authoring (#2035, ADR-0059) refused the block: it exported a bare
`: TranslationBundle` literal, which is the one pattern that rule exists to
keep out of the published catalog. The file's own canonical example already
says to prefer the factory over a bare literal, so the block contradicted its
own package — the inconsistency audit finding I18N-G-05 recorded from the
other side (the flagship shipped example does the discouraged thing).

The factory takes the wrapped values unchanged, so the shape the block teaches
is the same one; only the authoring form is now the one the skill prescribes.
Re-driven against the real exports before and after (throwaway driver in
packages/services/service-storage typechecking the exact block against
@objectstack/spec + @objectstack/platform-objects, tsc --noEmit exit 0,
deleted in the same step with a clean tree).
