Previously, the script attempted to assign GitHub Actions expressions directly within a Bash string using '${{ ... }}', which is invalid syntax in shell scripts. This caused the label JSON to be treated as a literal string instead of actual data, leading to parsing failures and incorrect backport readiness checks.
This update ensures the label data is passed correctly via the LABELS_JSON environment variable, allowing jq to properly evaluate label names and conditions.
Fixes: PKG-74
