#   - "n8n@X.Y.Z" - the versioned tag
#   - "stable"   - always points to the latest stable version
#
# We query the "stable" tag and extract the version from its target commitish (e.g., "release/2.18.5").
# This ensures we always get the actual latest stable version, not the most recently created tag.
