Maui api examples are inaccurate, obsolete, and don't compile

[Atezian]

Description

Steps to Reproduce

1. Create a new .net maui app project in VisualStudio 2022.

2. Copy and paste the grid example on the maui api docs.
   https://learn.microsoft.com/en-us/dotnet/api/microsoft.maui.controls.grid?view=net-maui-7.0

3. Observe how there is obsolete code. Also, Color.White for example that doesn't compile because Microsoft.Maui.Graphics.Color doesn't contain definitions for these properties. Adding anywhere up to 5 arguments into a method signature that only takes 1 argument. An attempt to call a method that doesn't exist (Device.OnPlatform(...)) Microsoft.Maui.Controls.Device.
