[FYI] {maint} hacking: don't reference ChangeLog anymore

[Stefano Lattarini]

* HACKING: Don't reference the ChangeLog file anymore, since that
is now generated from the git commit messages, not maintained by
hand.  So remove advice that is obsolete, and speak about "git
commit message" instead of "ChangeLog entry" for advice that is
still relevant.
