Remove use-wandb in doc

[xyao-nv]

Summary

Address https://nvbugspro.nvidia.com/bug/6062848

Detailed description

In a multi-GPU setup, the standard output (stdout) buffer gets flooded with logs from secondary GPUs. As a result, the wandb prompt requesting user input gets buried in the output. Because the prompt goes unanswered, the data loading process stalls, eventually leading to a timeout

Greptile Summary

Removes --use-wandb from the launch_finetune.py command snippets in three example workflow docs to fix a multi-GPU hang: in distributed training, secondary GPU stdout floods the terminal and buries the interactive wandb prompt, causing an unanswered input timeout that stalls data loading.

Note: osmo/finetune.yaml (not changed in this PR) still passes --use-wandb on line 69 and would encounter the same issue in that workflow path.

Confidence Score: 5/5

Safe to merge — documentation-only change with no code logic impact

All three files receive identical, targeted doc fixes (flag removal). No code, config, or test logic is altered. The remaining observation about osmo/finetune.yaml is informational and out of scope for this PR.

No files require special attention; all changes are straightforward documentation edits
