updated kaggle-Gemma3_(4B) notebook

[naimur-29]

Set tokenize=False in tokenizer.apply_chat_template
It won't run otherwise since the tokenizing is happening twice. I faced this minor issue when running today.

def apply_chat_template(examples):
    texts = tokenizer.apply_chat_template(examples["conversations"], tokenize = False) # here
    return { "text" : texts }
pass

tokenizer = get_chat_template(
    tokenizer,
    tokenize = False, # and here (inference and two other following cells)
    chat_template = "gemma-3",
)
