### Godot version

4.2.dev3.official

### System information

Godot v4.2.dev3 - Windows 10.0.19045 - GLES3 (Compatibility)

### Issue description

The toggle button "Show Built-In Actions" in the "Input Map" tab of the Project Settings window does not keep its ON state after restarting the editor - it always resets to being OFF.

This is different than the behaviour of the "Advanced Settings" toggle button in the "General" tab of the Project Settings - this one does keep its state between editor restarts.

I'm not sure if what I am reporting is an issue or the intended behaviour.

### Steps to reproduce

1. Create a new project.
2. Go to Project -> Project Settings -> Input Map and toggle "Show Built-In Actions" button to ON.
3. Restart the Godot editor.
4. Check if the setting was kept or changed.
