Fix undefined Docstrings reference by removing link temporarily

Keep the sentence but remove the {ref} link since python_essentials.md
(which contains the Docstrings label) hasn't been translated to Farsi yet.
Added TODO comment to restore link when translation is complete.

Fixes build warning: undefined label 'docstrings'

Fix writing_good_code reference warning

- Replaced broken {doc} link with plain text
- Added TODO comment to restore link once lecture is translated
- Build now completes without warnings

ENH: enable gh-actions workflows and setup as jupyter-book project
