### Godot version

v4.1.stable.official [970459615]  < Steam

### System information

Godot v4.1.stable - Debian GNU/Linux trixie/sid trixie - Vulkan (Mobile) - dedicated NVIDIA GeForce GTX 1060 (nvidia) - Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz (6 Threads)

### Issue description

After being upgraded to 4.1 via Steam (before any release announcement even! The speed!), I saw the warning marker against my game in the project manager, and noticed that the tooltip wasn't all that helpful:

![Screenshot_20230706_121443](https://github.com/godotengine/godot/assets/441188/7e62f67c-664f-4f5f-8f84-0cd0084679a6)

It seems to think that the old version number is a deprecated feature? :/

### Steps to reproduce

1. Have a project from Godot 4.0
2. Upgrade Godot to 4.1
3. Open project manager

Alternatively:
1. Create a new project in 4.1
2. Quit Godot
3. Edit the `project.godot`'s `config/features` to read `4.0` instead of `4.1`
4. Open project manager
