### Prerequisites

- [x] I have searched for [existing issues](https://github.com/ionic-team/ionic-framework/issues) that already include this feature request, without success.

### Describe the Feature Request

A new config property to set the default icon for detail-icon on ``. Just as it works for setting the default icon for ``

### Describe the Use Case

We want to use our own custom icon for items with `detail="true"` and having to add the `detail-icon` attribute on every item is a lot of effort and prone to design issues if a developer forgets to do it.

### Describe Preferred Solution

Add new config property

### Additional Information

There was the same feature request already in https://github.com/ionic-team/ionic-framework/issues/19906
The answer with a custom wrapper component that default sets the attribute is imho not satisfying as it poses one critical problem: A default component renders markup which makes the Ionic default styling for items in lists, etc. with first-child selectors etc. not work anymore. This kind of breaks the framework and is not a good proposed solution
