Regressed in:
https://github.com/vector-im/hydrogen-web/pull/769/files#diff-5432b565e86d2514c825ed9972c37ea19820bf12b5d8d3203fc9d4ea4654bd34L20 where the `const path = require('path');` was removed but we also started using `path` in more places which needed the same treatment.
When making the fix, we also have to make sure we don't also regress:

Fix:
```
$ yarn start
[vite] warning:
@theme/default
1 | import "C:\Users\MLM\Documents\GitHub\element\hydrogen-web\src\platform\web\ui\css\themes\element\theme.css";import "@theme/element/light/variables.css"
| ^
The above dynamic import cannot be analyzed by vite.
See https://github.com/rollup/plugins/tree/master/packages/dynamic-import-vars#limitations for supported dynamic import formats. If this is intended to be left as-is, you can use the /* @vite-ignore */ comment inside the import() call to suppress this warning.
Plugin: vite:import-analysis
File: @theme/default
```
And in the browser, it results in none of the styles loading because of the following error:
```
Uncaught SyntaxError: Invalid Unicode escape sequence (at default:formatted:1:163)
```

Before:
```
import { injectQuery as __vite__injectQuery } from "/@vite/client";import "__vite__injectQuery(C:\Users\MLM\Documents\GitHub\element\hydrogen-web\src\platform\web\ui\css\themes\element\theme.css, 'import')";import "/@id/__x00__@theme/element/light/variables.css"
```
After:
```
import "/ui/css/themes/element/theme.css";import "/@id/__x00__@theme/element/light/variables.css"
```
it's missing still:
- non-css assets like the download sandbox and the olm worker aren't written for some reason
- the es and cjs lib.js entry points end up in assets with a hash for some reason
- in these entry files, apart from our exports, something is adding an import statement for every import that was found in the tree
- all assets are hashed even though the config tries to disable that
- tests are included
