Subject: [PATCH] Fix name of started time field in shutdown status (#139910)

This commit adjusts the field name indicated the time a shutdown started
to be consistent with other millis based times, using the `_millis`
suffix with an underscore. Note that this API is private so making
rest changes without bwc is ok.

closes #139543
