   fix: https://github.com/apache/incubator-gluten/issues/11394
   
   The `UnsupportedOperators.tsv` report shows inflated operator counts that 
don't match the actual number of operator instances in the execution plan.
   
   For this execution plan:
   ```
   Execute InsertIntoHadoopFsRelationCommand (node 0, unsupported #1 - ROOT)
     └── Project (node 1)
         └── SortMergeJoin(skew=true) (node 2, unsupported #2)
             ├── Scan table1 (node 3)
             └── Scan table2 (node 4)
   ```
   
   **Expected**: 2 operators (1 InsertIntoHadoopFsRelationCommand + 1 
SortMergeJoin)
   **Actual**: 4 in the report
   
   In production event logs, the issue is more severe:
   - `Execute InsertIntoHadoopFsRelationCommand`: reported 62, should be 4
   - `SortMergeJoin(skew=true)`: reported 62, should be 4
