pages does not work for list_packages_for_organization

pages function returns only the first page of packages

```
api = GhApi(token=gh_token)
pack_pages = pages(api.packages.list_packages_for_organization, 5, org="my_org", package_type="npm")
for page in pack_pages:
for item in page:
print(item['name'])
```

this code will print name of the packages from the first page only
