refactor(types)!: Remove elements prop, change EdgeTypes/NodeTypes prop to string[]

* no more elements prop - v-model instead!
* Instead of passing an object map to components just pass in an array of strings as nodeTypes/edgeTypes object
* the string name will either be resolved to a dynamic component with :is="type" or a slot with the type-name
* update all examples
