[PATCH qemu-server master+stable-bookworm] check efi vars: promote message about missing MS 2023 certs to warning

[Fiona Ebner <f.ebner@proxmox.com>]

The expiration date of the MS 2011 UEFI certificates is June 2026 and
is getting closer, so the message about missing MS 2023 certificates
deserves to be a warning.
