chore: Add short_description translations for integration apps (#11562)

- Add short_description translations for integration apps (dyte, slack,
dialogflow, google_translate, openai, linear, shopify)
- Remove fallback logic in NewHook.vue since I18n.t() returns
translation key string when missing (making fallback ineffective)
