etherpad-lite: Start of docker image fails with error Cannot find module 'log4js' with DB_TYPE=sqlite

Describe the bug We upgraded to the latest etherpad release and now our etherpad installation refuses to start correctly. It fails with the following error:

etherpad    | Error: Cannot find module 'log4js'
etherpad    | Require stack:
etherpad    | - /opt/etherpad-lite/src/node/server.js

etherpad    | }

To Reproduce Steps to reproduce the behavior:

1. We use the following docker compose file

version: "3.7"

services:
  etherpad:
    image: etherpad/etherpad
    container_name: etherpad
    volumes:
      - type: bind
        source: TRUNCATED/etherpad/pads.db
        target: /opt/etherpad-lite/var/pads.db
    environment:
      - TITLE=TRUNCATED
      - DB_TYPE=sqlite
      - DB_FILENAME=var/pads.db
      - API_KEY=${ETHERPAD_API_KEY}
      - ADMIN_PASSWORD=${ETHERPAD_ADMIN_PASSWORD}
      - ADMIN_USER=TRUNCATED
    ports:
      - 127.0.0.1:13080:9001
    restart: unless-stopped
    command: bash -c "npm install sqlite3 && node src/node/server.js"

1. Run docker-compose up
2. Wait for the error

Expected behavior The docker container starts up normally.
