Examples - Creating a PlainDate from an object

What information was incorrect, unhelpful, or incomplete?

The chinese calendar spec is changed
https://tc39.es/proposal-intl-era-monthcode/#table-epoch-years

// Year, month, day in a different calendar
const d3 = Temporal.PlainDate.from({
  year: 2021,
  month: 7,
  day: 1,
  calendar: "chinese",
});
// Note: when you construct a date with an object, the date components
// are in *that* calendar, not the ISO calendar. However, toString() always
// outputs the date in the ISO calendar. For example, the year "2021" in
// the Chinese calendar is actually 616 BC in the ISO calendar.
console.log(d3.toString()); // "-000616-08-12[u-ca=chinese]"

above example shows different toString result 2021-08-08[u-ca=chinese]

What did you expect to see?

MDN can provide better example via choose other calendar like 'hebrew'
