feat: Make wrapNode protected

Make the function wrapNode as protected to allow overwriting

Thanks for the contribution but could you please share your usecase? This method is private intentionally because this is not part of the public API.

@bwaidelich In some cases the wrapper breaks the layout in the backend.
For example if I have a Grid-Node with Colum-Nodes in a collection.

The current behavior destroys the layout by putting a second div between elements where none should be existing.

<div data-_neos-form-builder-type="Foo.FormBuilder:Grid" >
    <div class="row">
        <div data-_neos-form-builder-type="Foo.FormBuilder:Column">
            <div class="col col-md-6">
                // Content
            </div>
        </div>
    </div>
</div>

How it is possible after the change:

<div data-_neos-form-builder-type="Foo.FormBuilder:Grid" >
    <div class="row">
        <div data-_neos-form-builder-type="Foo.FormBuilder:Column" class="col col-md-6">
            <div>
                // Content, the upper div doesn't have the classes in the backend
            </div>
        </div>
    </div>
</div>

<?php
namespace Foo\BaseFormBuilder\Fusion;

class FormElementWrappingImplementation extends \Neos\Form\Builder\Fusion\FormElementWrappingImplementation
{
    protected function wrapNode(NodeInterface $node, string $output, string $fusionPath): string
    {
        // [...]
    
        if ($node->getNodeType()->getName() === 'Foo.FormBuilder:Column') {
            $columnWidths = '';
    
            if ($node->hasProperty('widthXs')) {
                $columnWidthXs = $node->getProperty('widthSm');
                $columnWidths .= ($columnWidthXs != 'unset' && $columnWidthXs)
                    ? $node->getProperty('widthXs')
                    : '';
            }
            if ($node->hasProperty('widthSm')) {
                $columnWidthSm = $node->getProperty('widthSm');
                $columnWidths .= ($columnWidthSm != 'unset' && $columnWidthSm)
                    ? ' ' . $node->getProperty('widthSm')
                    : '';
            }
            
            $additionalAttributes['class'] = $columnWidths;
        }
        
        return $this->contentElementWrappingService->wrapContentObject($node, $output, $fusionPath, $additionalAttributes);
    }
}

Thanks for your thorough explanation. I'm reluctant to make this part of an extensible API because it will most likely break compatibility if the implementation is going to change.
If the backend layout is broken due to some invalid markup, we should report a bug and fix the root cause (similar to #27).

If this is just an issue with your specific markup, you could maybe adjust your CSS and/or the rendering of your custom form elements.
You could do that only for rendering in the Neos backend.
For example, to add some custom wrapping markup:

prototype(Your.Package:YourElement) {
    @process.wrap = ${'<div>' + value + '</div>'}
    @process.wrap.@if.inBackend = ${node.context.inBackend}
}

or, to add custom attributes:

prototype(Your.Package:YourElement) {
    @process.augment = Neos.Fusion:Augmenter {
        'custom-attribute' = 'custom-value'
    }
    @process.augment.@if.inBackend = ${node.context.inBackend}
}

does that help?
