fix: remove highlightResult from response (#337)

## 🧭 What and Why

🎟 Related Issue:

### Changes included:

there is a regression in the new api clients, we don't remove the
`highlightResult` anymore of the returned objects from the browse
response.

in the meantime of a fix there, we can fix it in the integration to
prevent different behaviors, as the API doesn't allow saving rules with
`highlightResult`
