Year in Fandom on wikia.com

This is being output straight to HTML without further escaping, so `->plain()` is not a [safe output format](https://one.wikia-inc.com/wiki/Engineering/Onboarding/Internationalization/Technical/Advanced#Outputting_messages_to_HTML) and should not be used as is. All of these messages should either be `->escaped()` or be escaped manually. I'm going to send a reminder about i18n output formats to the techteam as a follow up to the one I sent at the start of the year.
