Gemma 3n 4-bit finetune Q4_K_M GGUF support

[aphilas]

The finetuning Colab for Gemma 3n says that Q4_K_M is not supported:

    model.push_to_hub_gguf(
        quantization_type = "Q8_0", # Only Q8_0, BF16, F16 supported
 		# ...
    )

Is this still the case?

I have not attempted to run the Colab with Q4_K_M... yet. If I do I will update this discussion.
