Improving types

For boolean attributes, the correct value type would be:

type Boolean = `${boolean}` | boolean | undefined | null;

In order to write less code and to ensure that the types are always up-to-date and correct, they do not need to be written manually, but taken directly from the source:

import type { DatetimeChangeEventDetail, JSX } from "@ionic/core";
interface IonDatetime_Old {
    "clear-text"?: string;
    "on:ionChange"?: (event: CustomEvent<DatetimeChangeEventDetail> & { target: HTMLIonDatetimeElement }) => void;
}
type IonDatetime_New = {
    "clear-text": JSX.IonDatetime["clearText"];
    "on:ionChange": JSX.IonDatetime["onIonChange"];
};

But comments need to be copied.
