[REFACTOR] Prediction demo: use `CasePathResolver` of `bv-experimental-add-ons`

[tbouffard]

We are not using PathResolver in the demo for now as it is not considering edge in the input. See #520.

Needs

• [FEAT] CasePathResolver: add a method that returns the "full path" i.e compute both Shapes and Edges bpmn-visualization-addons#22
• [FEAT] Provide an IIFE bundle in the npm package bpmn-visualization-addons#26
• possibly [FEAT] CasePathResolver: distinguish completed and pending elements passed as input parameters to infer more flows/edges in the path bpmn-visualization-addons#16
