Redirect /trunk to /master #82
Description
Due to Ruby Issue 15843, the latest docs URL changed from https://docs.ruby-lang.org/en/trunk/ to https://docs.ruby-lang.org/en/master/. However, there are links in various third-party docs and online articles which point to pages in /trunk. These links now return a 404.
Is it possible to redirect /trunk to /master to fix them?
