FYI: Godot .NET 4.1/4.2 breakage upstream

[nanodeath]

Hi,

I've been trying to get my Godot 4.2.1 C# project publishing from a GitHub Action using this project, and many, but not all, of the scripts in the exported build just seem broken compared to a local editor play or local export.

This appears to be caused by godotengine/godot#85492, which talks about how C# exports break when the .godot directory is gone. Well, guess what -- we don't typically commit the .godot directory, so when CI is running, the directory is gone, and problems happen.

Just wanted to let people know about this as I've spent several hours trying to figure out what was going on 😞 and possibly could be the root cause of several issues (#126 at least),
