Fixed the import package example

So it is CurrencyConverter not sure why you put that probably a older version and forgot about it anyways this should work.

Hello, I see that you closed the PR, but I will leave a message for further reference.

• currencyconverter is the name of the git repo
• currency_converter is the name of the Python package that is installed and you need to import, visible here
• CurrencyConverter is the name of the Python archive uploaded to PyPI, configured here, and visible when running pip freeze after installation. This is also the name of the main class.

If I had to write this from scratch again I would probably try to unify names, but at the time I wanted to enforce usual naming conventions (I think).
