Fix resources filename mismatch when a dependency has a +

[fortmarek]

Resolves #6099

Short description 📝

The ResourcesProjectMapper would have a mismatch between referencing the bundle accessor file and the actual filename when the dependency had a +. To fix this, we no longer run camelized for the generated filename (I don't see why we'd need to do that).

How to test the changes locally 🧐

Integrating FirebaseAppMessaging-Beta via Tuist/Package.swift should work.
