resolve.alias is not working for $app/stores in sveltekit projects

### Describe the bug

I've checked another issues about `$app/stores`, but it seems like I have another issue.
It looks like resolve section in config ignores `$app/stores`:

When I try to use `$app/stores` in my story:

```js
import { page } from '$app/stores';
```
With following `histoire.config.ts`

```js
import { defineConfig } from 'histoire';
import { HstSvelte } from '@histoire/plugin-svelte';
import { resolve } from 'path';

export default defineConfig({
routerMode: 'hash',
plugins: [HstSvelte()],
vite: {
resolve: {
alias: {
'$app/stores': resolve(__dirname, './stores.mjs')
}
}
}
});
```
I get an error:
```
ReferenceError: __SVELTEKIT_APP_VERSION_POLL_INTERVAL__ is not defined
```

It worked fine with Histoire `0.11.2`, vite `3.5.2` and sveltekit beta

Start with the linked reproduction and its histoire.config.ts, then inspect src/lib/Test.story.svelte and run yarn story:build with the $app/stores import enabled. Done means the SvelteKit story build completes without the __SVELTEKIT_APP_VERSION_POLL_INTERVAL__ error while the configured alias remains usable.
