dozzle: User icon shows the "unavailable image link" icon

Describe the bug The following is shown: I suppose this is not intended behaviour.

To Reproduce I have the following docker compose config:

  dozzle:
    image: amir20/dozzle:latest
    container_name: dozzle
    restart: unless-stopped
    environment:
      - DOZZLE_AUTH_PROVIDER=simple
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./dozzle/data:/data
    ports:
      - 52043:8080

And the following in dozzle/data/users.yml

users:
  # "admin" here is username
  admin:
    name: "Admin"
    # Just sha-256 which can be computed with "echo -n password | shasum -a 256"
    password: "..."

I have tested with adding an email to the “admin:”, but also got the same icon.
