Adjust QWEN2 VL Loss rtol (#412)

## Summary

Closes #411

1. The convergence tests all passed in the latest commit
([PR#407](#407)). Its CI
worked fine:
https://github.com/linkedin/Liger-Kernel/actions/runs/11983838113/job/33413899589?pr=407#step:5:984

2. Without any code changes inside Liger, the convergence tests now
failed in QWEN2VL cases, referring to
#411.

The root cause of this is solely because huggingface released new
transformers which modified QWEN2VL.
Since it's not a bug within liger qwen2vl impl, it's okay to slightly
adjust the `rtol`s a bit.

BTW, seems there's some context maybe related:

## Testing Done

Yes.
