Svelte-kit package doesn't bundle css imports which are outside lib directory.

[SandipNirmal]

Describe the bug

I am creating a svelte-kit component library using svelte-kit package which packages everything from lib directory into a svelte package. I've a css file in src directory which I am importing in components. But when packaging css file is not copied to package directory.

Reproduction

Create a svelte-kit app with following structure.

src
 |
 |
 ___ index.css
 |
 ___ lib
      |
      |
      ___ Button.svelte
      |
      ___ index.js 

content of index.js

import './../index.css';

export {default as Button} from './Button.svelte'

When I am packaging this I expect css to be copied over since it's imported inside lib. But it doesn't.

This is expected as package command only looks at the contents of src/lib and copies them across as-is, see https://kit.svelte.dev/docs#packaging and its caveats.

You will need to move the css file inside src/lib or wait for #2572 to be resolved.
