Update the CI/CD workflows with latest Xcode version

[suho]

Why

Currently, all workflows are running on Xcode 14.2. We need to make sure our templates are runnable with Xcode 26. So, developers can also use the latest features and APIs from Xcode 26. It will also help to remove unexpected issues on the latest iOS version (iOS 26).

Acceptance Criteria

• Create new workflows to support running CI/CD on Xcode 26.
• Danger should work as expected.
• Be able to deploy new builds to Firebase/TestFlight.
