Use pospell

https://pypi.org/project/pospell/

There are Polish dictionaries available for hunspell (pospell), we could leverage it to improve the quality of the translation. It would require some configuration (extra custom dictionary and skipping code blocks). We could look at the other languages' setups.

% pospell --language pl tutorial/*.po

Start by reviewing the pospell command shown for tutorial/*.po, the linked discussion about skipping code blocks, and similar setups used by other languages. Configure the Polish translation checks with an extra custom dictionary and code-block handling, then verify that the command reports translation issues without flagging code or accepted terms.
