Typo on Optional Chaining (?.) Assignment

[kimhnh]

Hi, there is a small typo on the Optional Chaining (?.) assignment from codingheroes.io.

getFirstKeyword(book[0]);
should be: getFirstKeyword(books[0]); since the provided array is called books.

Hello @jonasschmedtmann,
It seems that the assignment material where this issue #414 occurs is not available in this repository. Could you please confirm if the content is hosted elsewhere? I would be happy to contribute if the file is accessible.

Thank you!
