Missing className prop in v7.4.0 breaks compatibility with styled-components typescript

[esetnik]

Describe the bug
The className prop is omitted from DatePickerProps which breaks compatibility with styled-components

https://github.com/Hacker0x01/react-datepicker/blob/main/src/index.tsx#L119

To Reproduce
Steps to reproduce the behavior:

import DatePicker, { DatePickerProps } from 'react-datepicker';
import styled from 'styled-components/macro';

const Input = styled(DatePicker)<{
  invalid: boolean;
}>`
  padding-inline-end: 40px;

  ::placeholder {
    color: ${({ theme }) => theme.grey60};
    font-size: 0.875rem;
  }

  background-repeat: no-repeat;
  background-position: right 8px center;

  ${({ invalid }) => invalid && 'border-color: #dc3545'}
`;

Expected behavior
No type error as in v7.3.0
