Godot 4.4 Mac fresh install ".NET assemblies not found" message when opening a project

### Tested versions

- Godot_v4.4-stable_mono_macos

Fresh install

### System information

MacOS Sequoia 15.3

### Issue description

Attempting to open a 4.2 project [Tanks of Freedom II](https://github.com/P1X-in/tanks-of-freedom-ii/tree/master/scenes) results in the following message:

I verified in package contents that `Contents/Resources/GodotSharp/Api/Debug` path exists in my `Godot_mono.app`

I verified that I'm using a C# distribution of Godot, which doesn't require any additional installs, but I also have .NET installed on my laptop as well.

### Steps to reproduce

- Download a fresh Godot_mono distribution: https://godotengine.org/download/macos/
- Clone [Tanks of Freedom II](https://github.com/P1X-in/tanks-of-freedom-ii) repo to any folder
- Open the project with Godot_mono.app
- See the popup

### Minimal reproduction project (MRP)

N/A

Start by reproducing the popup with a fresh Godot_v4.4-stable_mono_macos installation and the Tanks of Freedom II project. Inspect the Godot_mono.app package, especially Contents/Resources/GodotSharp/Api/Debug, and compare the reported assembly lookup with the available package contents. Done means opening the project without the ".NET assemblies not found" message.
