Orphan page in language tour: "Automatic Type-Dependent Closure Construction"

https://docs.scala-lang.org/tour/automatic-closures.html seems to be an orphan page that isn't in the language tour's table of contents and isn't linked to from within our site. I suspect its continued existence is just an oversight.

(I'm curious how someone even found the page to report the problem to us. Perhaps Google knows about it through an external link somewhere.)

I think we could just remove the page and replace it with a redirect to https://docs.scala-lang.org/tour/by-name-parameters.html
