Unless I'm wrong the new component name is org.nuxeo.ecm.core.scheduler.SchedulerService:

nuxeo-core/nuxeo-core-event/src/main/resources/OSGI-INF/scheduler-service.xml:
<component name="org.nuxeo.ecm.core.scheduler.SchedulerService">
  <alias>org.nuxeo.ecm.platform.scheduler.core.service.SchedulerRegistryService</alias>

You're right. I was less careful when fixing the example than when fixing our real config file apparently. I'll update the PR

We have aliases so the old names still work. This PR is just a cleanup.
