Disable advice warnings from PyTorch

There are a number of warnings in PyTorch that represent advice for
improving model, data loader, and training decisions. However these
warnings are confusing to end users and often aren't clearly relevant
even for advanced users. As a result, PyTorch supports disabling these
class of warnings, PossibleUserWarnings.

See:
https://lightning.ai/docs/pytorch/2.4.0/advanced/warnings.html
Lightning-AI/pytorch-lightning#10644

This change follows the recommended approach to hide these warnings
from users.
