Fix misleading executable path placeholder and add schema warning note in toast/snackbar setup docs

[Copilot]

The Windows setup instructions for Toast/Snackbar use YOUR-PATH-TO-EXECUTABLE without explaining how to determine the value, and users encounter an rescap:Capability schema validation warning with no guidance.

• Replaced placeholder YOUR-PATH-TO-EXECUTABLE → YOUR-PROJECT-NAME\YOUR-PROJECT-NAME.exe with an [!IMPORTANT] callout explaining the format:

  {.csproj file name without extension}\{.csproj file name without extension}.exe
  

  e.g., MyMauiApp.csproj → MyMauiApp\MyMauiApp.exe (matches the pattern used in the actual sample app)

• Added [!NOTE] that the rescap:Capability XML schema validation warning in Visual Studio is a false positive and safe to ignore

Both toast.md and snackbar.md include this shared file (toast-snackbar-setup.md), so both pages are fixed.

The 'Executable' attribute is invalid - The value 'YOUR-PATH-TO-EXECUTABLE' is invalid according to its datatype 'http://schemas.microsoft.com/appx/manifest/types:ST_ExecutableAnyCase' - The Pattern constraint failed.

The document does not mention YOUR-PATH-TO-EXECUTABLE except for the code it refers to copy/paste, or how to determine it.
