fix(datetime): remove datetime mock (#42)

resolves #18

Co-authored-by: anantoghosh <anantoghosh@users.noreply.github.com>

BREAKING CHANGE:

In Ionic v6, IonDatetime is no longer rendered as an overlay. As a result, the IonDatetime mock is no longer needed and has been removed. Developers can continue to use the real IonDatetime component imported from `@ionic/react`.
