Turn off "Mark as Solution" reminders for Suggestions and Feedback forums

[Oktokolo]

I posted in the [Oxygen Not Included: Spaced Out!] - Suggestions and Feedback forum and got an email asking whether the question has been answered and suggesting to use a "Mark as Solution" button on a reply.
Unsurprisingly for such a forum, i didn't post a question and there also isn't such a button on the replies (and it wouldn't make any sense to add one).

I guess, someone forgot to untick an option when creating that subforum.

P.S.: The email ironically also misses most text when displayed in text-only mode in Thunderbird (and probably any other email client).
