Review Comment:
This test is expected to pass even without the fix provided by this PR.
Currently, the extra columns returned to Spark do not cause any problems.
However, with [Comet](https://github.com/apache/iceberg/pull/9841) native
execution, since Comet allocates arrays in a pre-allocated list and relies on
the requested schema to determine the number of columns in the batch, this test
would fail without the fix proposed in this PR.
