SpringBoot Log ready time under 'spring.boot.application.ready' rather than 'spring.boot.application.running'

Currently SpringApplicationRunListeners logs ready time using spring.boot.application.running. I think we should change this to spring.boot.application.ready for consistency with the readiness probe support.

Do you mean renaming SpringApplicationRunListener#running to SpringApplicationRunListener#ready then? I am asking as we've just deprecated the version that doesn't take a Duration. Sounds like a good opportunity to redirect to the new method.

Yes. That should have been done already in a polish commit I recently pushed.
