Maybe a typo in the readme

This line:

```
if (!client.redirectUri != redirectURI) { return done(null, false); }
```

should be

```
if (client.redirectUri != redirectURI) { return done(null, false); }
```

because we are failing if the url is **not** the same.

Find the README line containing the shown redirectUri condition and compare it with the issue's proposed wording. Update the documentation so the snippet matches the requested condition, then review the rendered README to confirm the corrected example is displayed.
