🔧 chore(base.py): add method to remove unwanted base classes from the list of base classes

The `process_base_classes` method is added to the `FrontendNode` class. This method removes unwanted base classes specified in the `CLASSES_TO_REMOVE` list from the `base_classes` list. This ensures that only the desired base classes are included in the `base_classes` list. The method is then called in the `to_dict` method to ensure that the processed `base_classes` list is used when converting the `FrontendNode` instance to a dictionary.
