Copilot extension app refers to itself as 'test' in help and application menu

Open the GitHub copilot extension app from the dock, and click the 'Github Copilot for Xcode Extension' menu (phew, that's a long application name).

Observe that the first menu item is 'About test' .

Open the Help Menu

Observe that the first item in the menu is 'test Help'

### Expected results

The menu items should say 'About Github Copilot for Xcode Extension' and 'Github Copilot for Xcode Extension help'

Preferably a shorter name should be used for the application.

It doesn't give a great first impressions if you can't even set the application name correctly...
