Inheriting from Translation class in gdscript crashes the Editor & Game on startup

### Tested versions

Reproducible in 4.3.stable

### System information

Godot v4.3.stable - macOS 15.1.1 - Vulkan (Mobile) - integrated Apple M3 Pro - Apple M3 Pro (12 Threads)

### Issue description

I am trying to implement my own Translation Class in GDScript to do some data processing in the background. But when I try to use my own class (even when it's an emtpy class that just has name & extends Translation) and add this to the ProjectSettings->Localization the Godot Editor crashes when i reopen the project or when I start the game.
I can't get a log from the editor but the game when launched returns this crash in the log:
```

### Steps to reproduce

Create a GDScript class that extends Translation, create an Resource instance of it and set it under ProjectSettings->Localization.

```
@tool
class_name TranslationGoogleSheet
extends Translation
````

A simple class like this is enough.

### Minimal reproduction project (MRP)

This Project has the most simple Translation class & an instance of the resource set as localization. When you try to open the project the Godot Editor immediately crashes. To open the project, remove the Localization Setting from the project.godot file.
```locale/translations=PackedStringArray("res://test.translation")```

Start with the attached minimal reproduction project and the TranslationServer::_load_translations path shown in the backtrace. Trace the resource load into GDScriptParser::parse_identifier() and parse_class_name(), then verify that reopening the project and starting the game with the Translation-derived resource no longer crashes.
