C# wrapper(DialogueManager.cs) creates orphan nodes

[LeoVolcanoTheLion]

I found that this method in "dialogue_manager.gd" will result in an orphan node created every time a C# method is called using mutation.

Which may potentially causing a memory leak?
This my solution

I don't understand why Loading the DialogueManager.cs every time is necessarily, so I didn't change that.
"add_child(wrapper)" is not necessary, I just want the orphan nodes to remain 0.

I tried to give feedback on your YouTube channel a month ago, but YouTube keeps blocking my comments (those comments are only visible to me).
I asked a German friend of mine to leave a comment on your YouTube channel, but just in case I'll give feedback here as well XD

I've made some changes to the C# wrapper as part of #769 that should address those concerns: https://github.com/nathanhoad/godot_dialogue_manager/pull/769/files

The C# wrapper is now a RefCounted which gets cleaned up automatically when not in use.
