[I] cast `Utf8` to negative decimal failure [arrow-rs]

Weijun-H opened a new issue, #5127:
URL: https://github.com/apache/arrow-rs/issues/5127

   **Describe the bug**
   <!--
   A clear and concise description of what the bug is.

   **To Reproduce**
   <!--
   Steps to reproduce the behavior:
   -->
   
   ``` rust
       #[test]
       fn test() {
           let array = LargeStringArray::from(vec![Some("-0.12345")]);
   
           // Decimal128
           let output_type = DataType::Decimal128(38, 2);
           assert!(can_cast_types(array.data_type(), &output_type));
   
           let casted_array = cast(&array, &output_type).unwrap();
           let decimal_arr = casted_array.as_primitive::<Decimal128Type>();
   
           assert_eq!("-0.12", decimal_arr.value_as_string(0));
   
           // Decimal256
           let output_type = DataType::Decimal256(76, 3);
           assert!(can_cast_types(array.data_type(), &output_type));
   
           let casted_array = cast(&array, &output_type).unwrap();
           let decimal_arr = casted_array.as_primitive::<Decimal256Type>();
   
           assert_eq!("-0.123.", decimal_arr.value_as_string(0));
       }
   ```
   
   **Expected behavior**
