nebula.netflixoss 11.5.0

Pin release version to pull in fix for:

```
> Failed to apply plugin class 'nebula.plugin.release.ReleasePlugin'.
   > Git user.name is not set. Please configure git user.name globally, locally or system wide.
```

That can be removed when the transitive for netflixoss
is fixed.
