It's better to mention these types of issues at the issue itself (#1).
Its title had changed so @javascript-translate-bot couldn't recognize my PR (#93) and I wasn't a maintainer at the time. I updated it manually. :)

It was also translated in #19, and the title has changed since then. Updated that as well.

Thank you, @mahdiHashemi14!
