gce_workload_cert_refresh timer spams logs with error message

[Andrew Grigorev]

Currently available google-guest-agent version 20230426.00-0ubuntu2~22.04.0 contains a 10-minute systemd timer, which runs `gce_workload_cert_refresh` binary, which produce following error message on all (non-GKE?) Google Compute VMs:

> Error getting config status, workload certificates may not be configured: HTTP 404

Looks like this behavior is fixed in recent versions of google-guest-agent, like 1:20231115.00-g1 available for debian.
