Product name not escaped in ProductDataLayer

[fabrice-dresscodes]

If the product's name has apostrophs in the name, there is an issue with de javascript.

That's why I had to rewrite the ProductDataLayer to add the fuction htmlspecialchars

`

namespace XXXXX\Design\Block\Rewrite;

use KingfisherDirect\GoogleTagManager\Block\DataLayer;

class ProductDataLayer extends \KingfisherDirect\GoogleTagManager\Block\ProductDataLayer
{
public function configureDataLayer(DataLayer $dataLayer)
{
$product = $this->getProduct();

    if (!$product) {
        return null;
    }

    $dataLayer->push(['ecommerce' => null]);
    $dataLayer->push([
        'ecommerce' => [
            'detail' => [
                'products' => [
                    [
                        'id' => $product->getSku(),
                        'name' => htmlspecialchars($product->getName(),ENT_QUOTES),
                        'price' => $this->getProductPrice($product),
                    ]
                ]
            ]
        ]
    ]);
}

}
`
