Makefile: Include TEMPLATE_IMAGES in release artifacts

[vvoland]

• fixes: _images directory is empty in the released v2 tarballs #4313

The _images directory was missing from the output release tarballs because TEMPLATE_IMAGES was not included in the ARTIFACT_DES dependencies for the artifact targets.

---

Not sure if it's the correct fix, but it makes the _images present in the tarballs created by artifacts-darwin

$ make artifacts-darwin
$ tar --list -f _artifacts/lima-2.0.0.m-Darwin-arm64.tar.gz | grep _images
