Looping through an array shape has wrong count

[allejo]

Bug report

Given I'm using an array shape like array{bool, bool, bool}, it expects a key of int<min, 2>, where I would think it should be int<min, 3> or make it inclusive?

Code snippet that reproduces the problem

https://phpstan.org/r/eaaf2943-60db-49fa-9336-a2dead66c788

<?php declare(strict_types = 1);

class HelloWorld
{
	/** @var array{bool, bool, bool} */
	private $tuple;
	
	public function main(): void
	{
		$this->tuple = [true, true, true];
		
		for ($i = 0; $i < 3; ++$i)
		{
		    $this->tuple[$i] = false;
		}
	}
}

Expected output

I would think PHPStan should accept this code as valid.
