## Current Behavior
The `createConfig` helper from `@nx/angular-rspack` became an async
function.
This meant that the handling of custom webpack configs in the migration
done by `convert-to-rspack` was incorrect.
## Expected Behavior
Ensure the migration is handled correctly.
Ensure that Module Federation migrations work correctly.
