Replace all instances of save_handler=DiskSaver(...) with save_handler=path/to/dir

[Priyansi]

Since PyTorch-Ignite v0.4.7, we have updated save_handler in Checkpoint to pass the path to checkpoint directory rather than mentioning DiskSaver(checkpoint_dir, create_dir=True). It would be nice if this could be updated for all instances in this repository too. One such instance can be in under Checkpointing in How to convert PyTorch Code to Ignite.
