feat(template): add advanced flag to TemplateFieldCreator and FrontendNode classes

Add an advanced flag to the TemplateFieldCreator and FrontendNode classes to allow for fields to be hidden from the user interface. In the TemplateFieldCreator class, the advanced flag is set to False by default. In the FrontendNode class, the advanced flag is set to False for all fields except for "model_type" and "model_kwargs", which are set to True.
