fix(build): derive version from reachable git tag (#5711)

* fix(build): derive version from reachable git tag

* fix(build): fall back gracefully when no tag is reachable

git describe --tags --abbrev=0 exits with an error when the checkout has
no reachable tag (e.g. tagless forks or pre-first-tag commits). In the
Makefile this printed a fatal message and produced a bare -SNAPSHOT
version, and in the CI git-version step the non-zero exit would abort
the job under bash -e before the empty-tag guard could run. Silence
stderr and fall back to v0.0.0 in the Makefile, and to an empty string
in the workflow so the existing guard keeps skipping the output as it
did before.
