Fix compatibility with the lazy module

Problem/Motivation

If I use the lazy module, the pages don't validate.
Through attribute: loading="lazy"
I found an easy way to make the two modules compatible.

Steps to reproduce

Turn on AMP and lazy .

Proposed resolution

In file amp-image-wrapper.html.twig Replace:

{#
/**
 * @file
 * Theme override of an image.
 *
 * Available variables:
 * - attributes: HTML attributes for the img tag.
 * - style_name: (optional) The name of the image style applied.
 *
 * @see template_preprocess_amp_components_image()
 */
#}
<amp-img{{ attributes }}></amp-img>

On .removeAttribute('loading')

{#
/**
 * @file
 * Theme override of an image.
 *
 * Available variables:
 * - attributes: HTML attributes for the img tag.
 * - style_name: (optional) The name of the image style applied.
 *
 * @see template_preprocess_amp_components_image()
 */
#}
<amp-img{{ attributes.removeAttribute('loading') }}></amp-img>
