chore(platform-objects): regenerate the en metadata-forms bundle for the shared reference row's help text (#14892)

node scripts/check-i18n-bundles.mjs --write — the only bundle that moved; the
`reference` describe lives in no bundle. Clears the red `pnpm check:i18n` on
PR #15979's head b6f0313 (Type Check · consumer gates).
