Golden output for the tracing rendering helpers.

These functions are what the era tracing instances put into the log, and they were reimplemented off cardano-api when the instances moved here. Two of them silently changed shape in the process, which nothing caught -- hence these files. They pin the output as bytes so that a change to it has to be an explicit, reviewed change to a golden file.

A golden file is only ever as good as the review of the diff that created it: these were checked by hand against cardano-api-11.5.0.0, the version cardano-node used before the move.
