These are new jammy servers that are replacing older servers. They have
had their brains (db) transplanted from gitea01 to preserve redirects. I
have added their ssh host keys to the review02 private host vars.
Also we remove gitea08 from the replication list as it is no longer
behind haproxy and will be decommissioned. Doing this in a single change
reduces the period of time where replication events might be lost on
autoreload.
