build(pipeline): install the destinations tap in the image

meltano install would resolve it from pip_url, but five of the six custom
taps are also installed explicitly and a new plugin failing to appear is
not something you want to debug from a deploy log.

 5. **Bootstrap staging data via Airflow** (no prod dump — staging populates
    itself from source, exercising the pipeline image end-to-end):
-   - Set `AIRFLOW_ADMIN_PASSWORD` in the stack environment first. The
-     api-server refuses to start without it. Airflow's simple auth manager
-     otherwise generates a password on first start and writes it to a file, so
-     the login changes every time the container restarts; the stack writes that
-     file itself from this variable instead. `AIRFLOW_ADMIN_USER` defaults to
-     `admin`.
    - Open the staging Airflow UI (`http://<host>:8081`) and trigger, in order:
      `school_data_daily`, `school_data_monthly_ofsted`, then the manual-schedule
      `school_data_annual_ees` and `school_data_annual_idaci`.
