C# Example for Making plugins

[a2937]

Your Godot version: 4.1

Issue description: The last example is missing a C# equivalent. I'd like to that the C# versions of plugins can be automatically be loaded but I haven't tried to do this myself.

URL to the documentation page (if already existing):

Yes, registering autoloads with a C# plugin is supported. Pull requests to add the missing C# equivalent to the example are welcomed 🙂.
