Bias is not propagated when using TE
**Describe the bug**

When transformer_engine is enabled. NeMo doesn't pass the bias flag to the [AutocastTransformerLayer](https://github.com/NVIDIA/NeMo/blob/2cc09425aba3e9b3cfdba43a3188eaef58227055/nemo/collections/nlp/modules/common/megatron/transformer.py#L1014) in [ParallelTransformer](https://github.com/NVIDIA/NeMo/blob/2cc09425aba3e9b3cfdba43a3188eaef58227055/nemo/collections/nlp/modules/common/megatron/transformer.py#L846) so bias is always defaulted to True, despite the user trying to set it to False
