Unable to set accessibility name on SettingsCard's HeaderIcon image

### Describe the bug

The SettingsCard control have an accessibility issue that makes it unable to set an accessible name for the image used as HeaderIcon by the control, even when it is set manually when instantiating it.

### Steps to reproduce

Create a SettingsCard control with an image as a HeaderIcon (there is one in the sample gallery).
Add a AutomationProperties.Name to the image in the XAML.

### Expected behavior

The image will have its own accessible name as it was set up in the XAML, that can be narrated when keyboard focused. But there is none.

No, I'm unable to contribute a solution.

Locate the SettingsCard control and the sample gallery example that provides HeaderIcon. Review how AutomationProperties.Name is handled for the image, then reproduce the issue in the WinAppSDK/WinUI 3 sample; done when the manually assigned accessible name is available to keyboard focus and narration.
