# - If a version is provided, it will be used (with leading 'v' stripped if present).
# - If no version is provided:
#     * Uses the latest Git tag if available (with leading 'v' stripped if present).
#     * Otherwise, defaults to "dev-<short-hash>".
# - When running in GitHub Actions, uses "ci-<short-hash>" instead of "dev-<short-hash>".
