🐛 fix(validate.py): update input_types in template_field to ["Document", "BaseOutputParser"] for better accuracy

🐛 fix(base.py): remove "object" from CLASSES_TO_REMOVE list to prevent unnecessary removal
In validate.py, the input_types in the template_field for the "prompt" variable is updated to ["Document", "BaseOutputParser"] to accurately reflect the expected input types.

In base.py, the "object" class is removed from the CLASSES_TO_REMOVE list to prevent unnecessary removal of the "object" class from the FrontendNode class inheritance.
