Exporter getFailedNotificationBody

[MatticusPrime29]

There is a getCompletedNotificationBody method available for modifying the message of the export when the job succeeds. Although, if I pass in middleware that allows a job to fail via getJobMiddleware. E.g.,

public function getJobMiddleware(): array
    {
        return [
            ...parent::getJobMiddleware(),
            JobExceptionMiddleware::class,
        ];
    }

When the particular job fails, the message will still say whatever is passed into the getCompletedNotificationBody, without a way to tell if the job has failed such that the dev can change the error message.

If there could be a method called getFailedNotificationBody, that would be great! Even better to have the exception passed as a parameter to the method.
