Force Light theme makes certain controls not change colour

### Description

Picker has a hover of white text when forcing the light theme.

I've set the background so you can see the text colour.

Loaded page up, selected "This" from the picker:

If you hover over the item it'll turn white:

Since the light theme has a white background you can't read the text.

### Steps to Reproduce

1. Create new .NET MAUI app
2. Add a Picker such as
```

This
is
a
test

```
3. Go to App.xaml.cs and set `Current.UserAppTheme = AppTheme.Light;`
4. Set the background to something easier to see the difference e.g. `BackgroundColor="Green"` on the ContentPage
5. If you go select item from the picker then go to hover over it. The text will go from black to white and it's not readable.

Start with the public MauiLightBug reproduction and App.xaml.cs, then inspect how the Windows Picker handles hover styling when UserAppTheme is set to AppTheme.Light. Reproduce the unreadable white text on a light background and trace the relevant MAUI Windows control styling. Done means the Picker item text remains readable while hovered under the forced light theme.
