I just hit this today upgrading stable.  
In case it is helpful to anyone or someone can suggest a better way, this is my temporary solution:

```plaintext

hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - mkdir -p plugins
          - git clone https://github.com/discourse/discourse-voting.git
          - cd discourse-voting && git reset --hard 9b4f233b9d33a946f626597aaf3863d2305b8809 && cd ..

```
