[8.x] Fix DynamoDB locks with 0 seconds duration

[lukaszmtw]

I've added a default lock duration of 1 day for DynamoDB locks.

This makes the behavior consistent with DatabaseLock:

framework/src/Illuminate/Cache/DatabaseLock.php

Lines 92 to 95 in d425952

	protected function expiresAt()
	{
	return $this->seconds > 0 ? time() + $this->seconds : Carbon::now()->addDays(1)->getTimestamp();
	}

Fix #43280
