Clear DEVELOPMENT_TEAM in Xcode project

Remove hardcoded Apple team ID (9PAHLTG8AD) from Demo/What's New?.xcodeproj/project.pbxproj by setting DEVELOPMENT_TEAM to an empty string in both build configurations. This avoids leaking a private team identifier and makes the project more portable across environments.
