Outdated metadata directory

OS/device including version:
OS: NixOS 25.05.20241115.5e4fbfb (Warbler) x86_64
CPU: 12th Gen Intel i7-12700F (20) @ 4.800GHz

Issue description:

The extension is currently using an outdated metadata directory:

godot-csharp-vscode/src/godot-tools-messaging/client.ts

Line 228 in 55efe21

this.projectMetadataDir = path.join(godotProjectDir, '.mono', 'metadata');

The correct directory for Godot 4 should be .godot/mono/metadata. Because of this, the extension fails to provide any completions, outputting this error in the console:

[Extension Host] There is no Godot Ide Server running

Even though Godot is running and working (tested with nc localhost <port>).
