docs(partner-nodes): drop the transparent background claim for GPT Image 2

[lin-bot23]

Summary

ComfyUI #16744 removed the transparent option from the background input of the gpt-image-2 model; its options are now auto and opaque. The GPT Image 2 page still listed "Transparent background output" as a supported feature, which no longer applies to gpt-image-2.

Transparent backgrounds remain available on the 2.5 variants, and that is already documented on the GPT Image 2.5 page, so this removes the outdated bullet from the GPT Image 2 page only.

Files

• tutorials/partner-nodes/openai/gpt-image-2.mdx
• zh/tutorials/partner-nodes/openai/gpt-image-2.mdx, ja/tutorials/partner-nodes/openai/gpt-image-2.mdx, ko/tutorials/partner-nodes/openai/gpt-image-2.mdx (same bullet removed, hashes refreshed with pnpm translate:sync-hash)

Verification

• Confirmed against comfy_api_nodes/nodes_openai.py: gpt-image-2 uses _gpt_image_2_model_inputs(("auto", "opaque"), ...), while gpt-image-2.5-flare and gpt-image-2.5-sunburst keep ("auto", "opaque", "transparent").
• Diff contains only the removed bullet plus the refreshed frontmatter hashes.
