Fix dockerfiles
Running `make e2e` locally, I had the following error:

```
 => ERROR [e2e-worker-dataset-info 11/13] RUN poetry install --no-cache                                                                                                                                                                                                    0.4s

```

Adding the path fixes the issue.
