Using partial locale

[LWJerri]

Code

import { DayPicker } from "react-day-picker";

export function Start() {
  return (
    <DayPicker
      mode="range"
      locale={{ code: "ru" }}
      weekStartsOn={1}
      max={7}
      selected={selectedDate}
      onSelect={handleClickOnDate}
    />
  );
}

Expected Behavior

Property locale must have all fields as optional.

Actual Behavior

Can't just change localization in locale.

@LWJerri interesting, I see the reason of passing a partial locale there.
