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).
