From 3060c752f8bbc4852939ee7f15732e9752d0c6ec Mon Sep 17 00:00:00 2001 From: Derek Stevens Date: Tue, 31 Jan 2023 21:29:38 -0700 Subject: sort tags and deduplicate This sorts the tags reverse-chronologically. If any tags have the same name (shouldn't happen but it does in some of my repos), we use whichever one is "newer".
