`aspire new ... --non-interactive` fails without `--output`

```shell
aspire new aspire-starter -n SmokeApp --non-interactive
❌ An unexpected error occurred: Interactive input is not supported in this environment. Use the --non-interactive flag or ensure the CLI is running in an interactive terminal.
```

1- This should not suggest to use `--non-interactive` since it's provided
2- We should make it work with just a name (compute a unique foldern name if necessary, or use `./`)

I'd also wish we didn't require `--name`, for instance `dotnet new console` just works locally, using the current folder for the project name, we could behave the same way.
