Subject: [PATCH] CI/CD: Switch from gzip to XZ for archive compression
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To reduce the disk space consumption and upload/download times,
let's switch to a better archrive compression algorithm.
XZ should be popular enough to not cause many complaints about this.
