Replaced the error message in both Traditional and Simplified Chinese for "The \"%@\" shortcut can't be used because it's already used by a system-wide keyboard shortcut… Keyboard panel in System Preferences." with the equivalent found in macOS localization, which reads: "This keyboard shortcut is already in use by the system or another application. Please choose another shortcut or use Keyboard Preferences to customize other system shortcuts.". This phrase is found in SpotlightPref.lg in macOS localization.
