Extension thinks the Godot version is 3.x when there is no project

### Godot version

Master branch / none

### VS Code version

1.101.1

### Godot Tools VS Code extension version

geequlim.godot-tools 2.5.1

### System information

macOS 14.6.1 arm64

### Issue description

When VS Code is opened to the source code of [the Godot engine repository itself](github.com/godotengine/godot), and you open a `.gd` file in `modules/gdscript/tests/scripts/`, these errors appear:

Btw: I would also love to learn how to permanently hide the "Couldn't connect to the GDScript language server" popups. I open a lot of Godot projects in VS Code without Godot running, and my only option is to ignore each time. If I click the gear I only have the option to turn *on* all notifications.

### Steps to reproduce

Open the source code of [the Godot engine repository itself](github.com/godotengine/godot) in VS Code with this extension installed, and open a `.gd` file in `modules/gdscript/tests/scripts/`.
