Failed to import css with url() reference

Hi, @Akryum, vite-bundler is a great package to connect meteor with vite.
All is going fine, but vite-bundler failed to import css with url() reference.

I'm using the latest meteor 2.10, which is using `vite:bundler` package as the default solution for `vue` project.
So just run `meteor create --vue3 example` to generate a scarffold and add:

```js
// import/ui/main.js
import "sample.css"

// import/ui/sample.css
@font-face {
font-family: "remixicon",
src: url("remixicon.woff2") format("woff2")
}

// import/ui/remixicon.woff2 does exists.
```

It seems that `remixicon.woff2` file in css `url` is pointed to default `localhost:3000/....` not `localhost:5173/...` which is vite served.

In a standalone vite project, it is rebased to `localhost:5173/....` correctly.
