### Godot version

4.0-beta14

### System information

Windows 11 (10.0.22621)

### Issue description

When opening seemingly any project in the editor it will add the following to the project's `project.godot` file, if it wasn't already explicitly set previously:

```
[editor]

export/convert_text_resources_to_binary=true
```

... despite this already being the default value for this project setting.

This seems to be caused by #63312, which redefined this project setting with a different default value (`false`) from the original one (`true`).

https://github.com/godotengine/godot/blob/2ec0da1a75a066fe88986fc6ceda22fbabf7eedd/editor/export/editor_export_plugin.cpp#L230

### Steps to reproduce

1. Create a new project (or use the bundled one)
2. Open the editor
3. Close the editor
4. Note `export/convert_text_resources_to_binary=true` in the project's `project.godot` file
