Model alias not resolved to correct model for Github Copilot CLI

[GKersten]

Hi, I have an agentic workflow triggered with the following config

engine:
  id: copilot
  model: small

It compiled correctly using gh aw compile and the Model alias should be correct following these docs: https://github.github.com/gh-aw/reference/model-tables/

However when I trigger the workflow I get the following error by Github Copilot CLI:

Error: model 'small' is retired or unsupported. Did you mean 'gpt-4'?

gh aw version v0.81.6

Maybe they are starting to validate model names.
@copilot add a smoke-copilot-small agentic wormflows that writes a haiku with "small" model.
