SHA-1 self-signed keys are no longer exported to WKD
As sequoia followed upstream recommendations in regards to the deprecation of SHA-1 self-signed keys, these keys are no longer considered by the tooling when exporting for WKD.
This means we currently have a few keys, that are in user's local keyrings, but are no longer exported to WKD, which makes archlinux-keyring-wkd-sync fail (see https://bugs.archlinux.org/task/77634).
