Pod-app-resource.sh copy widgetExtension resource into main assets.car

[chenzhengang]

My xcasset only needs to be added to widgetExtension, and widgetExtension's own assets.car already contains these images, but these images are repeatedly added to the assets of the main app package.

I ignored the file in the script and it achieved the goal, but the script was automatically generated, so I still couldn't remove it. What should I do, I think this is a bug because cocoapod does not determine the target membership of the resource file.
