It would be nice to make the "Do nothing" Herald rule a bit more self-explaining.
To me, "do nothing" means, nothing is changed.
But probably, this rule means "Skip main action" or something like that.
[ ] understand the intended purpose of `HeraldDoNothingAction.php`
[ ] eventually improve `getHeraldActionName()` from "Do nothing" to "Skip main action"
