Pending&Skipped status on HTML reporter

[WassimMalouch]

This PR improves how multiple-cucumber-html-reporter handles pending statuses. Specifically:
If any step in a scenario is marked as pending, the entire scenario is now correctly reported as pending instead of skipped.
The calculation of pending scenarios and features has been fixed accordingly.
All logic changes are implemented in generate-report.js.

✅ Fixes / Enhancements
Accurate status classification for pending steps.
Ensures pending scenarios are reflected correctly at both the scenario and feature level in the final HTML report.
Improves consistency with step-level statuses.
