[MINOR][SQL][TESTS] Disable UI in SQL benchmarks by default

### What changes were proposed in this pull request?
Set `spark.ui.enabled` to `false` in `SqlBasedBenchmark.getSparkSession`. This disables UI in all SQL benchmarks by default.

### Why are the changes needed?
UI overhead lowers numbers in the `Relative` column and impacts on `Stdev` in benchmark results.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
Checked by running `DateTimeRebaseBenchmark`.

Closes #28432 from MaxGekk/ui-off-in-benchmarks.
