support CLI arg to select variant in create-cloudflare

I am trying to run
```sh
npm create cloudflare vite -- --framework=react --platform=workers --no-deploy  --no-git --lang=ts
```

And I still get asked to pick a "variant"
```
╰ Select a variant:
  ● TypeScript
  ○ TypeScript + SWC
  ○ JavaScript
  ○ JavaScript + SWC
```

How do I select this non-interactively? If I add `--accept-defaults` it seems to override all the other options.
