Adds empty placeholders for domains and data products in the UI. Consider avoiding template concatenation for the actionLabel to ensure proper translation support.

✅ 1 resolved

✅ Quality: actionLabel built by concatenating translated strings

📄 openmetadata-ui/src/main/resources/ui/src/components/DataMarketplace/MarketplaceDataProductsWidget/MarketplaceDataProductsWidget.component.tsx:260-263 📄 openmetadata-ui/src/main/resources/ui/src/components/DataMarketplace/MarketplaceDomainsWidget/MarketplaceDomainsWidget.component.tsx:243-246
The action label is assembled via template concatenation ${t('label.new')} ${t('label.data-product')}. Concatenating separately-translated fragments breaks word order and spacing in many locales (and RTL languages like ar-sa/he-he), so the rendered button text can be grammatically wrong. Prefer a single interpolated i18n key such as t('label.new-entity', { entity: t('label.data-product') }) (or a dedicated create-entity key) so translators control the whole phrase.
