* feat: use stable version 4
* feat: explicitly use the latest LTS version of Debian
* feat: set NODE_ENV to production, in case dependencies use it
* fix: use non-fixed versions of Debian dependencies, as they can be removed (!!!) from the registry
* ci: disable docker dependencies version fix
* ci: add explanations about Docker linting rule deactivation
