Proposed squash commit message

Adjust project and gitlab ci configuration

• Add Cobertura Reporter to angular-frontend/karma.conf.js as required by ci pipeline (see angular-frontend/.gitlab-ci.yml for more informationen).
• Remove Docker Template for CI Pipeline, as this template does not fit to this GitLab instance.
• Remove renovate.json5 Bot, as this is not given in Open Logistics Foundation GitLab.
• Remove ci-settings.xml, as this file is a duplicate to ci_settings.xml.
• Adjust ci_settings.xml to use GitLab artifact registry.
• Update README.md, angular-frontend/README.md and java-backend/README.md with information about Licenses of third-party dependencies.
