The script method should accept string as single parameter

Just a small QoL idea. 

This:
```
$this->ViteScripts->script([
    // files that are entry files during development and that should be served during production
    'files' => [
        'webroot_src/main.ts',
    ],
]);
```

should be equal with this:

`$this->ViteScripts->script('webroot_src/main.ts');`

Yay or Nay?
