git-artifacts: reset pkgrel=1 between releases

In case some update was necessary between releases, we need to increment
the `pkgrel` so that we can deploy new `mingw-w64-git` package versions.

However, the next release should reset that `pkgrel` back to 1.

Noticed by Matthias Aßhauer in
git-for-windows/git#4692 (comment).

The script that is used to build `mingw-w64-git` has been adjusted
accordingly in git-for-windows/build-extra#534
and with this change, we use the new `--reset-pkgrel` option.
