Description

FilePicker.PickMultipleAsync() can return null.
The documentation is correct, but the nullable reference type annotation for the return value is wrong.

https://learn.microsoft.com/en-us/dotnet/api/microsoft.maui.storage.filepicker.pickmultipleasync?view=net-maui-9.0#microsoft-maui-storage-filepicker-pickmultipleasync(microsoft-maui-storage-pickoptions)

Steps to Reproduce

var fileResults = await filePicker.PickMultipleAsync(PickOptions.Default);

// Warning: Expression is always true according to nullable reference types' annotations
if (fileResults is not null)
{
   // Some code
}
