Bug: api_google_nano_banana2_image_edit template references removed node GeminiNanoBanana2V2

The template templates/api_google_nano_banana2_image_edit.json contains a node of type GeminiNanoBanana2V2, but the only node currently installed on Comfy Cloud is GeminiNanoBanana2 (no V2 suffix), with a different widget signature.

This is a top-30 template by usage (7,847 runs per the cloud search_templates listing) and currently fails on cloud with:

Workflow validation failed — unknown node type(s): "GeminiNanoBanana2V2"

Reproduction

curl -sS -L https://raw.githubusercontent.com/Comfy-Org/workflow_templates/main/templates/api_google_nano_banana2_image_edit.json \
  | python3 -c "import json,sys; d=json.load(sys.stdin); print({n.get('type') for n in d['nodes']})"
# {'GeminiNanoBanana2V2', 'LoadImage', 'SaveImage'}

vs. cloud's installed node (via the comfyui-cloud MCP search_nodes tool):

{"name": "GeminiNanoBanana2", "display_name": "Nano Banana 2", "category": "api node/image/Gemini", ...}

Note: also a parameter-shape mismatch, not just a name mismatch

Renaming GeminiNanoBanana2V2 → GeminiNanoBanana2 is not sufficient. The template's widgets_values use the old V2 schema; the current GeminiNanoBanana2 schema is different:

Current GeminiNanoBanana2 required widget order:

prompt, model, seed, aspect_ratio, resolution, response_modalities, thinking_level

After patching node type only, cloud rejects with:

"value_not_in_list" — aspect_ratio = "MINIMAL" (was meant for thinking_level)
"value_not_in_list" — response_modalities = "randomize" (control_after_generate value)
"value_not_in_list" — thinking_level = "IMAGE" (was meant for response_modalities)

So the template's widgets_values array is also in the old V2 order and needs to be re-mapped, or the V2 variant of the node needs to be reinstated on cloud.

Suggested fix

Either:

1. Republish the template using the current GeminiNanoBanana2 node + correct widget order, or
2. Restore GeminiNanoBanana2V2 as a still-installed compatibility alias on cloud.
