directory-rename-detection.txt: update references to regression tests

The regression tests for directory rename detection were renamed from
t6043 to t6423 in commit 919df31955 ("Collect merge-related tests to
t64xx", 2020-08-10); update this file to match.  Also, add a small
clarification to nearby text while we're at it.
