[FEAT] Add a demo that shows the usage of plugins providing "by-name" APIs

[tbouffard]

Is your feature request related to a problem? Please describe.

We are developing new plugins providing methods by name :

• [FEAT] Introduce a plugin to expose the bpmn-visualization "CSS classes API" with names as parameters #73
• [FEAT] Introduce a plugin to expose the bpmn-visualization "overlays API" with names as parameters #74
• [FEAT] Introduce a plugin to expose the bpmn-visualization "style API" with names as parameters #75
• [FEAT] Introduce a plugin to expose the bpmn-visualization "elements API" with names as parameters #76

A demo would demonstrates plugins usage and new features.

Describe the solution you'd like

We could replicate the elements identification demo developed in bpmn-visualization

• list all elements by name in a drop down (function to be developed specificly for the demo) OR free input box to let the user searches for elements by name
• highlight the found element(s)
• specific highlight when several elements match ([FEAT] Improve robustness of BpmnElementsSearcher #3)
• when selecting a name, apply overlays / CSS / updateStyle to the element (using plugins "by-name")
• display the semantic information of the match element in a dedicated zone
