feat: Allow replacing the DatePicker's icon through props.

[ldelia]

Currently, there is no easy way to change the default DatePicker's icon.

Expected Behavior 🤔

 <DatePicker 
    {...props} 
    icon={<IconComponent />}
/>

Workaround

import {DatePicker as RRDatePicker} from "react-rainbow-components";

const Holder = styled.span`
  float: left;
  position: relative;
  width: 100%;
  & i {
    position: absolute;
    top: 6px;
    right: 18px;
    background-color: blue;
  }
`;

const CustomDatePicker = styled(RRDatePicker)`
  svg {
    display: none;
  }
`;

const DatePicker = (props: DatePickerProps): JSX.Element => {
    return (
        <Holder>
            <CustomDatePicker {...props} />
            <AssetIcon assetName={"Calendar"} />
        </Holder>
    )
}
