Unexpected token and octokit deprecation error

I'm running a simple example dangerfile.js straight from the docs, using the latest 7.0.2:

```js
import { message, danger } from 'danger';
import { readFileSync } from 'fs';

const modifiedMD = danger.git.modified_files.join('- ');

message(`Changed Files in this PR: \n - ${modifiedMD}`);
```

and `yarn danger local` throws both syntax error and deprecation notice:

```
> yarn danger local
yarn run v1.13.0
$ /node_modules/.bin/danger local

### Dangerfile

---------^
```

Am I missing something?

Start with the documented dangerfile.js example and the runner paths named in the trace, especially distribution/runner/jsonToDSL.js and distribution/runner/runners/inline.js. Reproduce with yarn danger local and trace the syntax and Octokit deprecation errors; done means the example evaluates successfully without these failures.
