Fix build errors in BranchSDK target

- Fixed Package.swift syntax error on line 1 (removed extra 'c' character)
- Moved BNCConfig.h from Private to Public group in Xcode project to match actual file location at Sources/BranchSDK/Public/BNCConfig.h

These changes resolve compilation errors where BNCConfig.h could not be found during builds.
