[ai-backend]: Gemma's activation function should be approximate GeLU and not exact GeLU.
Changing the activation function to gelu_pytorch_tanh.if you want to use the legacy gelu, edit the model.config to set hidden_activation=gelu instead of hidden_act. See huggingface/transformers#29402 for more details.
