Cannot expand tabs to full width on iOS

[JuanFcoMiranda]

Description

On iOS I have created an example like the one on the documentation with some tabs on the top of the page:

https://learn.microsoft.com/en-us/dotnet/maui/fundamentals/shell/tabs?view=net-maui-8.0#bottom-and-top-tabs

But I was expecting to expand the tabs to fulfill all the witdh. On Android I made a ShellRenderer and a ShellTabLayoutAppearanceTracker to achieve this, but it is not working on iOS, even creating the ShellRenderer and the ShellTabBarAppearanceTracker.

Another expected behavior that does not work, is the ability to swipe with between the tabs with a swipe gesture, like other multiplatform frameworks do.

Steps to Reproduce

1. Create some tabs on the top of the screen as the official documentatiion shows
2. Create a custom ShellRenderer
3. Create a custom ShellTabBarAppearanceTracker.
4. Add both files to MauiProgram
