### Godot version

4.1.stable.flathub

### System information

Ubuntu 22

### Issue description

I'm converting my project and just caught the version 4.0 in _`"to work in Godot 4.0"`_ instead of current version. I'm not sure if it's intended but I feel like it would make more sense to have current version or just 4.x

### Steps to reproduce

Try converting a project to Godot 4 from Godot 3

### Minimal reproduction project

Default Godot 3 project opened with Godot 4
