### Godot version

4.0.stable, 4.1.3.stable, 4.2.rc1

### System information

Fedora 38, GeForce RTX 4090 (NVIDIA 535.129.03)

### Issue description

`--rendering-method mobile` doesn't *actually* make a Forward+ project use the Mobile rendering method, even though the command line output says so.

### Project using Forward+ rendering method

### No CLI argument (use Forward+)

Looks like Forward+.

### `--rendering-method mobile`

#### `--rendering-method gl_compatibility` (or `--rendering-driver opengl3`)

### Steps to reproduce

- Use `--rendering-method mobile` to [run a project from the command line](https://docs.godotengine.org/en/latest/tutorials/editor/command_line_tutorial.html) that uses Forward+ in its project settings.
- Alternatively, use `--rendering-method forward_plus` on a project that uses the Mobile rendering method.
