[SPARK-40382][SQL][TESTS][FOLLOW-UP] Make the tests pass with ANSI enabled

### What changes were proposed in this pull request?

This PR is a followup of #37825, that change the types in the test relation to make the tests pass with ANSI enalbed.

### Why are the changes needed?

To recover the test coverage. Currently it fails with ANSI mode on: https://github.com/apache/spark/actions/runs/3246829492/jobs/5326051798#step:9:20487
