### Godot version

4.0.dev (d0398f62f0)

### System information

Windows 10

### Issue description

`PlaceholderTexture2D::size` property is registered as a `Vector2I`: https://github.com/godotengine/godot/blob/0daa86d70e7338506c37bee6b6e0c4aba7255d68/scene/resources/texture.cpp#L3389  
It should be a `Vector2`, as setter method use a `Vector2` and so parent class getter method.

### Steps to reproduce
