upgrades: Unattended upgrades does not update tzdata package

This is due to the updated package not matching any of the currently configured allowed matches for unattended-upgrades:

Checking: tzdata ([<Origin component:'main' archive:'stable-updates' origin:'Debian' label:'Debian' site:'deb.debian.org' isTrusted:True>, <Ori gin component:'main' archive:'stable-updates' origin:'Debian' label:'Debian' site:'mirror.hetzner.com' isTrusted:True>])

Currently configured:

Unattended-Upgrade::Origins-Pattern {            
//      "origin=Debian,codename=${distro_codename}-updates";    
//      "origin=Debian,codename=${distro_codename}-proposed-updates";
        "origin=Debian,codename=${distro_codename},label=Debian";                                                                              
        "origin=Debian,codename=${distro_codename},label=Debian-Security";                                                                     
        "origin=Debian,codename=${distro_codename}-security,label=Debian-Security";
        "o=Debian Backports,n=${distro_codename}-backports,l=Debian Backports";
}

This may be remedied by adding:

      "origin=Debian,codename=${distro_codename}-updates";

To /etc/apt/apt.conf.d/60unattended-upgrades.
