[MINOR][cudf_polars] Validation summary skips query failures

[nirandaperera]

Description

When there are query failures, the validation summary shows,

Validation Summary
==================
✅ All validated queries passed.

This is technically correct, but masks the fact that some queries failed. Need to inspect the json to find out what really happened. This is misleading.

This PR, fixes the reporting string when there are failed queries.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Report both validation failures and skipped queries.

Both branches use elif, so mixed failures produce an incomplete validation summary. Keep the non-zero exit code, but also list every affected query category.

• python/cudf/cudf/pandas/_benchmarks/utils.py#L759-L763: print skipped query IDs even when validation_failures is non-empty, and show the success message only when both failure collections are empty.
• python/cudf_polars/cudf_polars/streaming/benchmarks/utils.py#L1235-L1239: apply the same independent reporting logic.
