As for now, it is not possible for the user to create a slice item to an array tree node.
Description
We need to add the UI allowing the user to choose between a normal item or one of the available slices for an array node.
Additional context
Available slices have to be present in the node definition
Slice item creation has to respect cardinality constraint (we cannot create more slices than what is defined in its definition max attribute => This is to be handled in #613
