Docker brings up Homebridge outdated version 1.4.1 instead of 1.6.0
### Current Situation

I have set up a new mini computer during last week and installed the docker image oznu/homebridge via Portainer.

I am wondering, why is the v1.4.1 of Homebridge loaded and the Web Interface offers me directly the upgrade to 1.6.0, which works fine. But as soon as I restart the container, I am back on 1.4.1. There are no older images or something like this. Is this happening for a reason?

`version: "3.3"
services:

  homebridge:
    image: oznu/homebridge:latest
    container_name: Homebridge
    network_mode: host
    restart: unless-stopped
    environment:
      - PGID=1000
      - PUID=1000
      - HOMEBRIDGE_CONFIG_UI=1
      - HOMEBRIDGE_CONFIG_UI_PORT=880
    volumes:
      - data_homebridge:/homebridge
      
volumes:
  data_homebridge:
    driver: local-persist
    driver_opts:
      mountpoint: /opt/data/homebridge
    `
