Still more broken URLs after the redesign

Per https://github.com/expressjs/expressjs.com/pull/2333#issuecomment-4763243709, I think you guys think all the 404s introduced by the migration are fixed now, but this is not the case. I reran my script from https://github.com/expressjs/expressjs.com/issues/2332#issuecomment-4499884195 (with a tweak to ignore the www.expressjs.com.cn domain) and found the following old URLs (taken from Stack Overflow posts) that are currently 404ing: * https://expressjs.com/en/changelog/4x.html#4.16.0 * http://expressjs.com/2x/guide.html#req.param%28%29 * http://expressjs.com/en/guide/writing-middleware.html\|Writing * http://expressjs.com/guide.html#configuration * https://expressjs.com/tr/guide/routing.html * https://expressjs.com/en/changelog/4x.html * http://expressjs.com/en/guide * http://expressjs.com/faq.html * http://expressjs.com/guide.html#executable * http://expressjs.com/guide.html#route-middleware * https://expressjs.com/ru/guide/routing.html * http://expressjs.com/guide.html#routing * http://expressjs.com/2x/guide.html * http://expressjs.com/guide.html#res.cookie%28%29 * http://expressjs.com/migrate.html * http://expressjs.com/applications.html * http://expressjs.com/faq.html#multiple-statics * https://expressjs.com/en/resources/template-engines.html * http://expressjs.com/en/index.html * http://expressjs.com/guide.html#users-online * http://expressjs.com/guide.html#creating-a%20server * http://expressjs.com/guide.html#view-rendering * http://expressjs.com/guide.html * http://expressjs.com/ru/starter/static-files.html * http://expressjs.com/guide.html#error-handling * http://expressjs.com/guide.html#passing-route%20control * http://expressjs.com/tr/api.html#req.method * http://expressjs.com/guide.html#passing-route * http://expressjs.com/tr/api.html#req.body * http://expressjs.com/guide.html#proxies At least some of these (e.g. https://expressjs.com/en/changelog/4x.html, http://expressjs.com/ru/starter/static-files.html) were working URLs shortly before the redesign (confirmed via ad-hoc checking in the Wayback Machine), though some were not (e.g. the FAQ page has, I think, been dead for many years); I leave it to y'all to unpick which are which. But certainly there are at least several URLs in the list above that still deserve a fix.
