[tests] fix deepspeed zero3 config for `test_stage3_nvme_offload`

[faaany]

What does this PR do?

Since we manually modified the original zero3 config value here, we will end up with a ValueError in accelerate (code).

For Zero3 Checkpointing, we need to turn this value to True.

Oh, that's a mis-click. This is the correct line: https://github.com/huggingface/accelerate/blob/main/src/accelerate/accelerator.py#L3278
