This commit upgrades helm.sh/helm/v3 from v3.20.0 to v3.20.2 to address a security vulnerability related to Chart.yaml extraction directory collapse. The vulnerability allowed specially crafted Charts to write contents to the immediate output directory rather than the expected subdirectory during 'helm pull --untar' operations. Changes: - Updated go.mod: helm.sh/helm/v3 v3.20.0 -> v3.20.2 - Updated go.sum with new dependency checksums Build verification completed successfully.
