StatelessVisualisation uses expanded definiton of a pre-existing type

[PennyJim]

StatelessVisualisation::nested_visualisations uses the type or array[type] format despite StatelessVisualisations already being that.

This is intentional, it reflects how it is loaded internally.

Actually, putting this back into unresolved because StatelessVisualisations might allow more than the currently documented format, so that should be investigated.

Seems all fine, updated the docs for the next release to use StatelessVisualisations for nested_visualisations.
