Missing package product when adding local package

This was mentioned in a resolved thread. I'm not sure if the described fixed is legit: https://github.com/yonaskolb/XcodeGen/issues/721#issuecomment-2196428321

Here's my project.yml

From what I can tell, Xcode shows an alright configuration:

Start with the supplied project.yml, especially its packages and target dependencies, and compare the generated Xcode project with the linked resolved thread. Reproduce the missing package product configuration and verify that local package products appear correctly in the generated project.
