Fix Playwright PR commenter false-positives when tests are skipped

This PR fixes the issue where the PR comment bot incorrectly reports "All tests passed" when Playwright tests are skipped or don't run.

Changes:
1. Modified test-ui.yaml to capture and upload test status as deployment-info artifacts
2. Modified pr-playwright-deploy.yaml to properly handle missing test results

The fix ensures that:
- Test exit codes are properly captured and passed between workflows
- When tests are skipped, the comment clearly states "Tests were skipped or not run"
- Each browser test result is tracked individually with proper status reporting

Fixes #5338
