In https://jira.camunda.com/browse/OPT-4039, we add a new query param for the frontend to filter for definition keys for Camunda definitions that can be used in event based processes. Once the Frontend has migrated to this new parameter, the existing excludeEventProcesses parameter can be removed as it will no longer be used.
- The deprecated query parameter is removed
- All tests using this parameter are removed/updated to use new param
- API documentation is updated
