fix(bot): reword gateway channels error so GitGuardian stops flagging it

GitGuardian's Generic CLI Secret detector reads
'pass --token and/or --set key=value' as '--token <secret>'. Since #6082 merged,
every PR that merges main carries that line and fails the GitGuardian check,
which the merge gate treats as a CI failure.
