[9.x] Cleaning up old if-else statement

[coleshirley]

This old (and ugly) if else statement was discovered in the Laravel discord so I figured I'd PR it for better readability.

An alternative syntax with less right hand side arms:

return match (true) {
            $this->shouldQuit => static::EXIT_SUCCESS,
            $this->memoryExceeded($options->memory) => static::EXIT_MEMORY_LIMIT,
            $this->queueShouldRestart($lastRestart),
            $options->stopWhenEmpty && is_null($job),
            $options->maxTime && hrtime(true) / 1e9 - $startTime >= $options->maxTime,
            $options->maxJobs && $jobsProcessed >= $options->maxJobs => static::EXIT_SUCCESS,
            default => null
        };
