fix: only show Failed Tests section when there are actual failures (#8575)

## Description

The Playwright test comment was showing a "❌ Failed Tests" section
header even when there were only flaky tests (no actual failures). This
was confusing because the red X suggested failure when tests actually
passed.

**Before:** Shows "❌ Failed Tests" section for flaky-only runs
**After:** Only shows "❌ Failed Tests" section when there are actual
failures; flaky tests are treated as passing
