This commit improves multiple aspects of Docker builds:
- Enable artifact output validation for Dockerfile.
- Correct the path references in Dockerfile for the distribution
directory.
- Add Dockerfile specific indentation rules to `.editorconfig`.
- Use `npm run install-deps` for dependency installation, enhancing
build reliability.
- Add automation script `verify-web-server-status.js` to verify running
web server on given URL.
- Introduce automated build verification for Dockerfile:
- On macOS, install Docker with colima as the container runtime
because default agents do not include Docker and Docker runtime is
not installed due to licensing issues (see actions/runner-images#17).
- On Windows, there's no Linux container support (actions/runner#904,
actions/runner-images#1143), so keep the checks for macOS and Ubuntu
only.
