[SPARK-24598][DOCS] State in the documentation the behavior when arithmetic
operations cause overflow
## What changes were proposed in this pull request?
According to the discussion in https://github.com/apache/spark/pull/21599,
changing the behavior of arithmetic operations so that they can check for
overflow is not nice in a minor release. What we can do for 2.4 is warn users
about the current behavior in the documentation, so that they are aware of the
issue and can take proper actions.
## How was this patch tested?
NA
