✨ Add more common text metrics from torchmetrics.

[jacklanda]

What does this PR do ?

Simply, add more common text metrics from torchmetrics.
It takes me long time to find out how to add more common text-based metrics for validation measurement in NeMo, and I hope this PR could help more people to get to know that ``Yes, we can leverage more auto metrics directly from torchmetrics.''.

To re-run CI remove and add the label again.
