Display quickfix versions in news

[shaunlebron]

Sometimes David will post a quickfix version after a release. For example, 1.9.211 was immediately fixed by 1.9.216, but the news post title still signals the older version.

Perhaps in news/index.edn, I can allow a :quickfix-versions [] attribute, which we can reflect in the title somehow.

• put the last quickfix version in the title: "1.9.211216 - cljs.spec fixes"
• make a blank redirect page for 1.9.211 and all but the last quickfix version -> 1.9.216
  • we can do this if we care about avoiding dead links
• the version table can cross out the versions superseded by quick fixes
  • or only link the releases not superseded by quick fixes

I'm gonna keep this simple and just rename the file when quickfixed.
