This means we do not need to worry anymore about manually syncing the pre-push
git hook or the Guix-provided git configuration.
* etc/git/gitconfig: Augment configuration template with useful options to
allow for auto-configuration.
* Makefile.am (.git/hooks/pre-push, .git/config): New targets.
(nodist_noinst_DATA): New primary variable holding the above targets.
This is a follow-up to commit 9fc8ae4171, which
missed two hunks from <https://issues.guix.gnu.org/50363>.
Reported by hackeryarn on #guix.
* .gitattributes, etc/git/gitconfig: New files.
