Proposed Changes

This implements the event types change. The legacy name is displayed in a label and can be changed in a one-way manner.
We could consider displaying the unknown name in the select too, but this means it will still appear in the options to select.

Requires camunda/camunda-bpmn-js-behaviors#92 to be released and integrated.
