It would be great to be able to pass an optional generic for select and multiselect prompts to narrow down what type the options might be, e.g.:

type PackageManager = 'npm' | 'pnpm' | 'yarn'

await consola.prompt<PackageManager>(...)

giving us a more precise return type: Promise<PackageManager> (select) or Promise<PackageManager[]> (multiselect)
