^ Should be able to have a From<proxmox_sys::boot_mode::BootMode> here.

Since the info we get isn't nested anymore, we could just move the match
inside the struct building.

    BootModeInformation {
        mode: bm.into(),
        sb: sb.into() or sb == SecureBoot::Enabled with the added Eq
    }

Btw. I'm not even sure we should have the above function if we query it
all at this point anyway, this could also just be
BootModeInformation::query(), or the function above could just take no
parameters.
