### Godot version

4.1.1

### System information

linux

### Issue description

The `"%+f"` format adds a `+` sign in front of positive numbers. If you try to format `-0.0`, it breaks and displays both a `+` and a `-`.

### Steps to reproduce

```gdscript
@tool
extends EditorScript

func _run() -> void:
    print("%+f" % -0.0)
```

### Minimal reproduction project

 * For translations that can be supplied by exported projects, use `RTR()` instead.

 * `vformat(TTRN("%d item", "%d items", some_integer), some_integer)`.
 * The placeholder must be present in both strings to avoid run-time warnings in `vformat()`.
