Use Ruff formatter in devcontainer config (#3737)

Fixes #3736

Description:
- Replace `ms-python.black-formatter` with `astral-sh.ruff` in
`.devcontainer/devcontainer.json`
- Set Ruff as the default formatter for Python files in VS Code
devcontainer settings
- Remove the remaining Black-specific formatter configuration

Check list:
- [ ] New tests are added (if a new feature is added)
- [ ] New doc strings: description and/or example code are in RST format
- [ ] Documentation is updated (if required)
