    FLINK-7369: Add more information for `Key group index out of range of key group range`
exception

    When i got the following exception log, it make me confused that the index is more than
`32` or less than `16`. So, we should add more information for it.
    
    ```java
    java.lang.IllegalArgumentException: Key group index out of range of key group range [16,
32).
