fix(vercel-edge): Make breadcrumbs option optional in WinterCGFetch integration (#10785)

Right now it's not possible to use it as:

```js
new Sentry.Integrations.WinterCGFetch({
  shouldCreateSpanForRequest: (url) => {
    return !url.startsWith(`${process.env.NEXT_PUBLIC_SUPABASE_URL}/rest`);
  }
})
```

due to `breadcrubs` not being marked as optional. Instead of changing it
to such, reuse already existing `Options` interface to keep it in sync
with the integration itself.
