upgrade cog default version

Hi,

Thanks for this helper, smoothing cog deployments!
The current default version is set to `v0.9.8`, which prevents installs with CUDA 12.8 version which is not supported.
Suggested change:
```
  cog-version:
    description: "The version of Cog to install"
    required: false
    default: "v0.16.10"
```

If this doesn't involve any side effect and can be integrated as is, I can propose a PR.
