Storefront

Removed only variable scoping so that page, section and block variables are available in included templates in these files:
- src/Storefront/Resources/views/storefront/element/cms-element-cross-selling.html.twig
- src/Storefront/Resources/views/storefront/page/product-detail/cross-selling/tabs.html.twig
- src/Storefront/Resources/views/storefront/page/product-detail/index.html.twig
