[PATCH] ci: use actions/{upload,download}-artifact@v3

[Junio C Hamano <gitster@pobox.com>]

GitHub CI jobs stopped complaining about use of deprecated actions
that requires deprecated Node.js 12 for some steps, thanks to a
recent work by Oscar Dominguez to upgrade actions/checkout from v2
(which required Node.js 12) to v3 (which runs with recommended
Node.js 16).

Upgrade actions/upload-artifact and actions/download-artifact from
v2 to v3, following suit.

 * The CI run hasn't finished, but it seems to be doing well
   https://github.com/git/git/actions/runs/3627513480

   We are also getting complaint about our use of set-output command
   that is deprecated, which will need to be addressed, too.
