installation issues Exception: Config option `ckan.datapusher.api_token` must be set to use the DataPusher.

i get the below errors even after running

`docker stop $(docker ps -q); docker rm $(docker ps -aq); docker image rm $(docker image ls -q); docker network rm $(docker network ls -q); docker volume rm $(docker volume ls -q)` followed by `docker system prune `

then

```
docker compose build
docker compose up
```

```
