### 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 Godot got upgraded 4.0 -> 4.1, when opening a project from the earlier version, I noticed that the buttons in the confirmation dialog look a bit squiffy:

(Somewhat aside, but that dialog should probably be able to deduce and be more precise about whether it's an upgrade or downgrade!)

### 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
