Errata: Flashcards Set 3 Card 45 Typo

[Kilian Reisenegger]

As the subject implies, I've found a typo in flashcards set 3 card 45:

System.out.println(Duration.ofMills(123));

should be

System.out.println(Duration.ofMillis(123));

Correct! I've added it to the errata I plan to submit a bunch of them to the publisher to try to get the website fixed in the next month.
