@spectrum-icons/workflow dependency is missing

If you chose the react app with aio app init, when you try to build the app you will face the issue: Error: Cannot find module '@spectrum-icons/workflow'

This seems to be because an icon from that package is imported here

generator-aio-app/generators/add-web-assets/exc-react/templates/src/components/ActionsForm.js

Line 31 in 0e7e61b

import Function from '@spectrum-icons/workflow/Function'

but the dependency @spectrum-icons/workflow is never defined see

generator-aio-app/generators/add-web-assets/exc-react/index.js

Lines 55 to 64 in 508b42c
