Feature Request / Improvement

Current Spark smoke test runs on Hive Catalog, it would be nice if we run the same test cases on top of REST Catalog as well. Example: https://github.com/apache/iceberg/blob/main/spark/v3.5/spark-runtime/src/integration/java/org/apache/iceberg/spark/SmokeTest.java

Query engine

As discussed offline, I think the we can build on top of RCK classes from #10908 for REST Catalog based spark integration tests.
