[Windows] TabBarDisabledColor is not applied when the TabBar is in a disabled state

[NafeelaNazhir]

Description

When a Tab is disabled (IsEnabled = false), the TabBarDisabledColor property is expected to change the icon and text color of the disabled Tab.
This works correctly on Android , but on windows the TabBarDisabledColor is not applied, and the TabBar continues to use the default system disabled color.

Steps to Reproduce

1. https://github.com/dotnet/maui/blob/inflight/candidate/src/Controls/tests/TestCases.HostApp/Issues/Issue32995.cs
2. https://github.com/dotnet/maui/tree/main/src/Controls/tests/TestCases.HostApp/FeatureMatrix/Shell/ShellTabbed
3. Set TabBarDisabledColor="Green" in the Shell.
4. Disable one of the tabs.
5. Run the sample on Windows.
6. Observe that the disabled Tab does not use the green color and instead shows the default disabled color.
