Use `dash:DetailsEditor` instead of `dash:BlankNodeEditor`

[dennisvang]

The default schemas specify a dash:BlankNodeEditor where a dash:DetailsEditor would probably be more appropriate.

For example, the publisher should be rendered as a nested form with editable fields:

FAIRDataPoint/src/main/resources/org/fairdatapoint/database/fixtures/shape-resource.ttl

Lines 22 to 28 in 6a1de45

	], [
	sh:path dct:publisher ;
	sh:node :AgentShape ;
	sh:minCount 1 ;
	sh:maxCount 1 ;
	dash:editor dash:BlankNodeEditor ;
	], [

However, the specified dash:BlankNodeEditor is supposed to be read-only:

Rendering: a read-only editor that displays the blank node similar to dash:BlankNodeViewer yet allows the surrounding user interface to at least provide a delete button.

On the other hand, the dash:DetailsEditor does render as nested form with editable fields:

Rendering: typically rendering as a nested form, using the properties defined by the sh:node or sh:class (in that order) of the property as fields. [...]
