[@fujocoded/expressive-code-output] Dynamic require of "path" is not supported error

Hi,

I'm trying to use your `expressive-code-output` plugin, following the doc, and I get this error as soon as I try to run `astro dev` with this import in my `astro.config.ts`:

```ts
import { pluginCodeOutput } from "@fujocoded/expressive-code-output";
```

Error:

```
> astro dev --host

Any idea what can be going wrong?

These are my dependencies

```

Beginne damit, den Fehler beim Plugin-Import in astro.config.ts und bei astro dev zu reproduzieren. Untersuche die generierte dist/index.js rund um den dynamic require und vergleiche sie mit der Build-Konfiguration des Pakets. Die Aufgabe ist abgeschlossen, wenn das Plugin importiert werden kann und der Entwicklungsserver von Astro die Konfiguration ohne den dynamic require-Fehler laden kann.
