"""Pin the ordinal-suffix helper used by the monthly-schedule label in tasks.js.
_scheduleLabel built the suffix with `d === 1 ? 'st' : d === 2 ? 'nd' : ...`,
which only handles single digits, so a monthly task on day 21/22/23/31 rendered
"Monthly on 21th"/"22th"/"23th"/"31th". The shared ordinalSuffix() fixes this.
