🔧 Fix Docker deployment (#1070)

Fix the Docker build, which failed on the last deployment

Also:

- Add the new `plotting` extra, to install `matplotlib`
- Makes the docker build workflow run (without deployment) in PRs that modify the Docker files,
- fixes deprecation warning in workflow: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/
