fix(api-nodes): remove "veo2" model from Veo3 node

[bigcat88]

Bug was accidentally made in this PR yesterday.: #10357 , where I put all models in:

MODELS_MAP = {
    "veo-2.0-generate-001": "veo-2.0-generate-001",
    "veo-3.1-generate": "veo-3.1-generate-preview",
    "veo-3.1-fast-generate": "veo-3.1-fast-generate-preview",
    "veo-3.0-generate-001": "veo-3.0-generate-001",
    "veo-3.0-fast-generate-001": "veo-3.0-fast-generate-001",
}

and use keys from it to pass to Combo
