RangePicker dont use the locale correctly

[DominikGri]

Bug report 🐞

Version & Environment

• Version of browser: Chrome Version 89.0.4389.72
• Version of Conflux-Chain/react-ui: 2.0.0

Expection

The RangePicker should be displayed in german. Days and Months should be translated correctly

Actual results (or Errors)

The RangePicker is still in english. Even if the locale of dayJs locale is 'de' (output of dayjs.locale()).

import locale from '@jnoodle/rc-picker/lib/locale/de_DE'
import 'dayjs/locale/de'

dayjs.locale('de')

<RangePicker
  format="DD. MMMM YYYY"
  locale={locale}
  ranges={{
    Today: [dayjs(), dayjs()],
    'This Month': [dayjs().startOf('month'), dayjs().endOf('month')],
  }}
  onChange={onChange}
/>

I could offer you to add a new locale, as a pull request. If this is possible ?
