In https://github.com/camunda/product-hub/issues/248, Zeebe will add support for BPMN Link Events. We should support these in Optimize in the following ways:

• Processes rendered in Optimize should correctly display the process with the correct BPMN symbl
• Data imported from such a process should be usable in reports

ATs:

• We have an IT to verify data import from processes that contains a BPMN Link event
• We verify that these processes work in the Optimize UI as expected

Testing Notes:

• This is C8 only. Focus on the UI testing, by deploying a process containing a link event and using data from such a process in a report
