ci-artifacts: build with NO_RUST for the time being

Since the minimal Git for Windows SDK ci-artifact comes without Rust,
and since Rust is _not yet_ mandatory in Git, let's build without the
Rust parts in the `ci-artifacts` workflow.

This recapitulates what the person driving that mandatory Rust business
themselves did in `ci/lib.sh` in git/git's 32d5b90590 (Enable Rust by
default, 2026-04-09).
