@LiuQhahah , please fix the ci and test failures like CatalogIcebergBaseIT#testUpdateIcebergColumnDefaultPosition

Looks like there's some style issue needs to be fixed, @LiuQhahah would you please fix it.

There're some residual logic to process DefaultColumnPosition in IcebergTableOpsHelper.java, do you like to remove it in this PR?

  private void doUpdateColumnPosition(
      UpdateSchema icebergUpdateSchema,
      UpdateColumnPosition updateColumnPosition,
      Schema icebergTableSchema) {
    StructType tableSchema = icebergTableSchema.asStruct();
    // not need any more
    ColumnPosition columnPosition =
        getColumnPositionForIceberg(tableSchema, updateColumnPosition.getPosition());
    doMoveColumn(icebergUpdateSchema, updateColumnPosition.fieldName(), columnPosition);
  }
