Fix generating CoreData models in resourceSynthesizer .coreData()

[alexfilimon]

Resolves #6200

Short description 📝

I have realized that during project mapping, resources and CoreData models are explicitly separated in the project structure (Target.resources and Target.coreDataModels). However, in the SynthesizedResourceInterfaceProjectMapper class, when generating code from templates, the search for files is done only in Target.resources. When generating the CoreData template, it looks for files with the xcdatamodeld extension, which are located in Target.coreDataModels.

• I have modified it to search for the appropriate files for code generation in both resources and coreDataModels.
• I have also enhanced the tests in SynthesizedResourceInterfaceProjectMapperTests, and running these tests before my changes will result in failures.

How to test the changes locally 🧐

1. Create a project with .coreData() resourceSynthesizer
2. Run the tuist target with the parameters (generate, --no-open, --path /path/to/project)
3. Make sure that the TuistCoreData+AppCore.swift file appears in the tuist Derived folder

Thanks a lot for the PR! The changes look good – however, can you update the ios_app_with_coredata fixture, so it would have failed without your changes?

[alexfilimon]

Yes, of course. @fortmarek thanks for the suggestion.
I updated the fixture ios_app_with_core_data and checked that without my fix this test was failing

[fortmarek]

Thanks for updating the fixture! We can merge this after the lint pipeline is fixed (you need to run mise run lint:fix. Also, if we can update the coredata template file, that'd be amazing
