content: ion-password-toggle example has bad import statement

### URL

https://ionicframework.com/docs/api/input-password-toggle

### Issue Description

The example under Basic Usage has
```
<script setup lang="ts">
  import { IonInput, InputPasswordToggle } from '@ionic/vue';
</script>
```
the 2nd import is wrong. It should be IonInputPasswordToggle.

Cheers.
