ipabusedb-docker-reporter: pin docker CLI image, add make push, fix stale names

Pin the docker:cli source to 29.9.3 plus its manifest list digest, tag
the image as git.eeqj.de/sneak/ipabusedb-docker-reporter with the date
and latest, add a push target, and rename the remaining
ipabusedb-docker-ssh references in the README and package doc.
