Re: [PATCH v2 2/3] doc: interpret-trailers: don’t use deprecated config

>
> `command` has been deprecated since commit c364b7ef51 (trailer: add new
> .cmd config option, 2021-05-03).
>
> Use the commit message of c364b7ef51 as a guide to replace the use of
> `$ARG` and to use a script instead of an inline command.[1] Also,
> explicitly trigger the command by passing in `--trailer=see`, since
> this config is not automatically used.[2]

> [1]: “Instead of "$ARG", users can refer to the value as positional
>    argument, $1, in their scripts.”
> [2]: “At the same time, in order to allow `git interpret-trailers` to
>    better simulate the behavior of `git command -s`,
>    'trailer.<token>.cmd' will not automatically execute.”
