Description of changes

Recently, there have been cases where our pull request validation builds in ci.yml would fail, but the pipeline would still be marked as successful. This makes two changes to resolve this:

• Include set -o pipefail to handle failures in the build itself, not just in xcbeautify
• Remove continue-on-error so the stage will fail properly

Verification

Builds with broken issues (as tested earlier in this PR) actually fail checks and are blocked from merging!

Pull request checklist

This PR has considered:

• Light and Dark appearances
• iOS supported versions (all major versions greater than or equal current target deployment version)
• VoiceOver and Keyboard Accessibility
• Internationalization and Right to Left layouts
• Different resolutions (1x, 2x, 3x)
• Size classes and window sizes (iPhone vs iPad, notched devices, multitasking, different window sizes, etc)
• iPad Pointer interaction
• SwiftUI consumption (validation or new demo scenarios needed)
• Objective-C exposure (provide it only if needed)
