[PATCH] gitk: use the 'reference' format for the commit reference

From: Beat Bolli <dev+git@drbeat.li>
Date: Aug 27, 2020, 16:12 UTC
Message-ID: <20200827161224.824365-1-dev+git@drbeat.li>

Since 1f0fc1db85 (pretty: implement 'reference' format, 2019-11-19) in the main Git repository, there's an officially blessed format for commit references. Update gitk to also use this format.
