Fixed bug where list index privileges was returned twice instead of list item index (#75256)

## Summary

Fixes a bug where the list privileges was returning the `.list` privileges twice instead of returning it once and returning the `.items` privileges second with the call. No UI has to change as the way it was written was dynamic to grab the first key found.

This also adds the functional tests to `x-pack/scripts/functional_tests.js` which was not there originally so the end to tend tests should actually run on the CI machine where it was not running on CI before.

Adds the functional tests to the code owners file as well.

Ensure that you go to the test results page from the Jenkins build:

And ensure you see the tests under:

```
X-Pack Lists Integration Tests
```

Then click through it and ensure they are shown as running and passing

### Checklist

- [x] [Unit or functional tests](https://www.elastic.co/guide/en/kibana/master/development-tests.html) were updated or added to match the most common scenarios
