Fix DerivedData lookup for project names that contain spaces

Build insights collection now correctly locates Xcode activity logs for projects and workspaces whose names contain spaces. Previously, when a project or workspace filename included a space (for example, “My Project.xcodeproj”), tuist inspect build failed to find the generated .xcactivitylog because Tuist looked under a DerivedData directory using the raw name, while Xcode writes logs under the same prefix with spaces replaced by underscores. The DerivedData locator now mirrors Xcode’s behavior, so activity logs are picked up correctly from schemes whose post-action runs tuist inspect build.
