Exporting NodePath as a C# array don't work

[AndreSacilotto]

Godot version

4.1.1 & 4.2-dev5

System information

win10

Issue description

The docs says it is possible to export NodePath in a native c# array, but in reality is not.
https://docs.godotengine.org/en/stable/tutorials/scripting/c_sharp/c_sharp_exports.html#exporting-c-arrays

Steps to reproduce

[Export] public NodePath[] NodePaths { get; set; }

And try to build you will receive a similar error message:
