test(bonfire): goldens for list, help and errors

- list, list --all, list --format=json and an --ansi styled list (D-13, D-16)
- admin:token:create help and a passthrough help; help <cmd> equals --help (D-14)
- error blocks: hint with {bin}, unknown command, -v chain on stderr (D-18)
- CheckDocs gaps in order and sorted; the version header and BuildVersion
- goldens render with color detection cleared; -update rewrites them
