[Php74] Do not remove Array Shape docblock on TypedPropertyRector

[samsonasik]

Given the following code:

final class DoNotRemoveArrayShapeDocblock
{
    /**
     * @var array{a: \stdClass[], b: \DateTime[]}
     */
    private $property = [
        'a' => [],
        'b' => [],
    ];

    public function getProperty()
    {
        if ($this->property['a'] === [] && $this->property['b'] === []) {
            $this->property['a'] = [new stdClass()];
            $this->property['b'] = [new \DateTime()];
        }

        return $this->property;
    }
}

It currently produce:

-    /**
-     * @var array{a: \stdClass[], b: \DateTime[]}
-     */
-    private $property = [
+    private array $property = [

which docblock shoult not be removed.

This PR try to fix it.
