Add a redirect at the top level (#336)

amartini51 · web-flow · commit 95945de6bc92 · 2024-12-04T13:36:32.000-08:00
Without this redirect, the server generates a directory listing for <https://docs.swift.org/swift-book/documentation/> and you have to click through to the actual content. This page uses a reduced version of the existing redirect page, with the majority of the JavaScript removed. Because we never hosted any pre-DocC content at this URL, there's no reason to inspect the fragment and do a more specific redirect. There aren't any old URLs that point here for us to avoid breaking. Fixes: rdar://137038334
