### Describe the Feature Request

Add `autocomplete` and `autocorrect` properties to `ion-textarea`.

### Describe the Use Case

Input has autocomplete and autocorrect props, but Textarea does not. Both props are available on native `` elements, so we should add the props too.

### Additional Information

Start by locating the ion-textarea component API and comparing it with the native element, which the issue identifies as the source of the desired behavior. Confirm how ion-input exposes its autocomplete and autocorrect properties, then add equivalent textarea support and verify that both props are accepted and passed through consistently.
