The issue only provides a ci-info listing of SSH public-key fingerprints and names, without identifying a file, command, or expected change. Start by locating where this infrastructure exposes or manages authorized keys, then determine which listed keys are still valid; done requires an agreed audit result and removal or retention decision for each key.
