[Feature]: Documents Editable

[kaurov]

Feature description

Curretly, templates/default/default.html.twig has no allowed editables, so any document created it not editable.

I believe that Skeleton for ANY application need documents to include at least some layout and to be editable.

Minimum:

{{ pimcore_areablock('content', {
            'allowed': ['blockquote', 'embed', 'featurette', 'gallery-carousel', 'gallery-folder',
                'gallery-single-images', 'headlines', 'horizontal-line', 'icon-teaser-row', 'image',
                'image-hotspot-marker', 'image-metadata', 'pdf', 'product-grid', 'product-teaser', 'standard-teaser', 'text-accordion',
                'time-slider-featurette', 'video', 'wysiwyg', 'wysiwyg-with-images', 'personalized-product-teaser']
        }) }}
