[TypeDeclaration] Skip property fetch on array dim fetch in StrictArrayParamDimFetchRector

[TomasVotruba]

Fix false positive: property fetch on $param[0]->$key means the param holds an object, not an array itself, so no array type should be added.

/**
 * @param object $object
 */
private function getDataForObject($object): mixed
{
    foreach ($object as $key => $value) {
        if (0 === $key) {
            continue;
        }

        $object[0]->$key = $value;
    }

    return $object[0];
}

Guard added in shouldStop(): stops when a PropertyFetch/StaticPropertyFetch targets $param[...].
