vite/rollup tree shakes lib/common.js

**Describe the issue/behavior that seems buggy**



I investigated a few issues (e.g. https://github.com/highlightjs/vue-plugin/issues/44) reported in the `vue-plugin` repo where production builds are stripping out `import 'highlight.js/lib/common';` side effect imports 



Turns out vite (which uses rollup internally) tree shakes side effect imports if the files themselves are not marked as side effect in `package.json`



**Sample Code or Instructions to Reproduce**



```

npm create vite@latest

npm install highlight.js

```



Then inside `src/main.ts`, add:



```

import 'highlight.js/lib/common'

import hljs from 'highlight.js/lib/core'

console.log(hljs.listLanguages())

```



In debug builds `npm run dev`, it should list all languages registered inside `highlight.js/lib/common`



However in production builds `npm run build && npm run preview`, it will print an empty array.



**Expected behavior**



Should print all languages in both debug/production builds



**Additional context**



This package.json should be updated to:



```

  "sideEffects": [

    "./es/common.js",

    "./lib/common.js",

    "*.css",

    "*.scss"

  ],

```
