title: With Jekyll, fix mistyped date without breaking old link
body: <p>I'm using Jekyll for my blog. I've added a new blog post <a href="http://lukaspuettmann.com/2019/09/22/automation-patents-paper/" rel="nofollow noreferrer">here</a>, where mistyped the URL name to be <code>/2019/09/22/automation-patents-paper/</code> (so it's the wrong year).</p>
  
  <p>This screws up the date at the top of the post and if I leave the date of the post at 2019 then it'll stay at the top of my <a href="http://lukaspuettmann.com/archive/" rel="nofollow noreferrer">list of posts</a> for two years ...</p>
  
  <p>But I've already shared the blog under this URL on social media and would like people to continue be able to get to the post through that link. I've send the link to some people by email that I would really like to click on it and not get to some <a href="http://lukaspuettmann.com/cl/2099/01/01/example-wrong-title-name" rel="nofollow noreferrer">404</a> page.</p>
  
  <p>If I republish the post with the correct name, is there some way to reroute the old URL to the new URL?</p>
