Update Gitlab CI MR

• Merged with main branch
• Experimented with the local docker, but didn't get it to work; consistently fails packing the conda env with the ncurses 6.3 error mentioned in the main MR description
  • changed Dockerfile to resemble the one used by gitlab ci as much as possible
  • moved the installation of wmf_workflow_utils from the Makefile to the Dockerfile, as it is already installed when running in CI
• Beware: after running (or attempting to) make env using local docker, the resulting dist directory will cause the autopep8 pre-commit hook to run for a loooong
