[Transformers + DeepSpeed] "Please correct the following DeepSpeed config values that mismatch TrainingArguments values ... set these DeepSpeed config values to 'auto'"

Cause (Documented platform behavior): Trainer cross-checks mirrored keys; auto bucket sizes derive from hidden_size. Fix status: documented_behavior Limitations: - Transformers docs also say some manual batch values that disagree continue silently with wrong values - not every key is cross-checked. Other error fragments: - The easiest method is to set these DeepSpeed config values to 'auto'. - therefore it's not possible to automatically fill out the following `auto` entries in the DeepSpeed config file: Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/huggingface/transformers/07338b6c74a578868368e6e549dea83414e4b8cb/src/transformers/integrations/deepspeed.py (official_docs, unknown, documented_behavior): trainer_config_finalize raises mismatches list; auto fill error for missing hidden_size. - https://raw.githubusercontent.com/huggingface/transformers/07338b6c74a578868368e6e549dea83414e4b8cb/docs/source/en/deepspeed.md (official_docs, unknown, documented_behavior): Docs: use "auto"; mismatched manual batch values can continue silently.
