Incorrect spelling suggestion for the Angolan currency Kwanza

The newest release of codespell requests this change:

• web_programming/currency_converter.py:26: Kwanza ==> Kwanzaa

Clearly, both are valid spellings for different things.

Yes, makes sense. Do not hesitate to suggest a merge request to fix that.
