updating list of scope dependencies

Attempting to follow docs to go through a standard export of tenant configuration using the auth0 CLI tool leads to a missing dependencies error.

via https://auth0.com/docs/extensions/deploy-cli/guides/import-export-directory-structure

```
me% a0deploy export -c config.json --strip -f directory -o export
...

2019-04-22T18:46:12.980Z - error: Problem running command export during stage load when processing type roles
2019-04-22T18:46:12.980Z - error: {"statusCode":403,"error":"Forbidden","message":"Insufficient scope, expected any of: read:roles","errorCode":"insufficient_scope"}
```

Adding `*:roles` permissions in the API that the newly created application is using fixes this, so proposing these changes to the docs to update requirements.
