Revert "RedirectSpecialPage: handle interwiki redirects."

This reverts commit 41106688abbe6dfff61c5642924ced42af3f0d33.

The original case is changed by this commit from a MediaWiki fatal
exception with HTTP 500, to a blank 200 response due to silent
failure. Use of GoToInterwiki appears to be invalid at this point in
the code. Reverting to keep prod the same as last week, so as
to unblock the train.

Bug: T227700
