docs: add Sage Attention speedup section to MiniMax H3 tutorial

[lin-bot23]

Add a new Speeding up generation with Sage Attention section to the open-weights MiniMax H3 tutorial page.

Sage Attention roughly doubles generation speed at 720p with minimal quality loss. The section covers:

• Installation: users install the sageattention package themselves (wheel from the SageAttention releases page matching their PyTorch/CUDA) plus the KJNodes custom nodes (Patch Sage Attention KJ)
• Workflow wiring: connect Patch Sage Attention KJ between UNETLoader and BasicGuider (model in / model out), set sage_attention to auto; only the guider needs the patch, not the scheduler
• Notes: fp16/bf16 fallback log messages are expected (MiniMax H3 runs some layers in other dtypes); alternative global option is the --use-sage-attn launch flag

All 4 language files updated with manual sync + hash sync.

Scope the Sage Attention speed claim to the reported benchmark.

The PR objective identifies the reported generation improvement at 720p. The current text presents the roughly twofold speedup without that condition. Scope every sentence to 720p and regenerate translation metadata after the text changes.

• tutorials/video/minimax/minimax-h3.mdx#L50-L50: scope the English claim to 720p.
• ja/tutorials/video/minimax/minimax-h3.mdx#L65-L65: scope the Japanese claim to 720p and refresh its translation metadata.
• ko/tutorials/video/minimax/minimax-h3.mdx#L66-L66: scope the Korean claim to 720p and refresh its translation metadata.
• zh/tutorials/video/minimax/minimax-h3.mdx#L66-L66: scope the Chinese claim to 720p and refresh its translation metadata.
