name-rev: replace --stdin with --annotate-stdin in synopsis

34ae3b7 (name-rev: deprecate --stdin in favor of --annotate-stdin,
2022-01-05) added --annotate-stdin to replace --stdin as a clearer
flag name. Since --stdin is to be deprecated, we should replace
--stdin in the output from "git name-rev -h".
