Restart chef-client.service after upgrade

[TimRots]

While upgrading Chef infra client 17.x to 18.2.7 chef-client.service is not restarted.
This will result in failing chef-client runs as shown below, until the service is restarted

chef-client[748]: [2023-04-26T07:49:43+00:00] INFO: SIGUSR1 received, will run now or after the current run

I would expect the chef-client.service to be restarted during the upgrade flow.
Can be reproduced by running kill -USR1 $(pidof ruby):
