Fix datetime.utcnow() deprecation warning

[malhotra5]

Summary

This PR fixes the deprecation warning for datetime.utcnow() which is scheduled for removal in a future Python version.

Changes Made

• Updated import: Added UTC to the datetime import in tests/integration/utils/consolidate_results.py
• Replaced deprecated method: Changed datetime.utcnow() to datetime.now(UTC) on line 57

Details

The deprecation warning was:

DeprecationWarning: datetime.datetime.utcnow() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.now(datetime.UTC).

The fix follows the recommended approach from the warning message and uses the modern timezone-aware datetime approach.

Testing

• ✅ All pre-commit hooks pass (ruff format, ruff lint, pycodestyle, pyright)
• ✅ Verified the function works correctly without deprecation warnings
• ✅ No functional changes - the behavior remains identical

Files Changed

• tests/integration/utils/consolidate_results.py: Updated datetime usage to use modern timezone-aware approach

Backward Compatibility

This change maintains full backward compatibility. The output format and functionality remain exactly the same, only the internal implementation uses the modern datetime API.
