Summary

This PR addresses issue #438 by clarifying how to use the deepcopy function in the Making the Board lesson.

The lesson previously mentioned deepcopy as an alternative to shallow copying but did not explain that it must be imported from Python's copy module.

Changes

• Added an explanation that deepcopy must be imported before use.
• Included the import example: from copy import deepcopy.
• Clarified how deepcopy(board) creates an independent copy of the board.
• Regenerated the English translation files to keep the course content synchronized.

Testing

• Reproduced NameError: name 'deepcopy' is not defined when using the function without importing it.
• Verified that importing deepcopy resolves the error and preserves the original board.
• Regenerated translation resources using poetry run python -m translations.generate_po_file.
• Ran poetry run pytest -k test_steps — 1 passed, 9 deselected.
• Ran git diff --check — passed.

This change only updates the course explanation and its translation resources; no application logic was modified.
