[PATCH v2] doc: interpret-trailers: fix cmd examples

[kristofferhaugsbakk@fastmail.com]

From: Kristoffer Haugsbakk <code@khaugsbakk.name>

Fix `trailer.<key-alias>.cmd` examples which have remained unchanged
since they were written in c364b7ef (trailer: add new .cmd config
option, 2021-05-03). (Modulo formatting changes.)

Steal how the `see` example is phrased and use that as a template:

    Configure a `see` trailer with a command to show the subject of a
    commit that is related, and show how it works:
