Render options correctly

[Baachi]

I debugged a little bit, why options are not rendered currently (as mentioned in #150). It seems that the Neos.Form.Builder:SelectOptionCollection/itemRenderer didn't fetched the properties, it just returns null which is stripped out by the implementation.

fixes #150

@dlubitz You had touched this implementation with #144 – can you judge whether this fix makes sense? To me it seems sensible, but I don't know all the implications

Thank you @Baachi for this PR. But this fix might work, but isn't correct at this place. The Neos.Form.Builder:SelectOptionCollection is not aware of the items it get's passed. This needs to be implemented on the using side.

See: https://github.com/neos/form-builder?tab=readme-ov-file#dynamic-options

In this case AFAIS it needs to be implemented here:

form-builder/Resources/Private/Fusion/NodeBased/NodeBasedFormElement.fusion

Lines 15 to 20 in 3ec4c7d

	[email protected] = Neos.Form.Builder:SelectOptionCollection {
	items = ${q(elementNode).children('options').children()}
	valuePropertyPath = 'properties.value'
	labelPropertyPath = 'properties.label'
	@if.isSelectFormElement = ${q(elementNode).is('[instanceof Neos.Form.Builder:SelectionMixin]')}
	}
