Helm Chart extraction output directory collapse via `Chart.yaml` name dot-segment

Helm is a package manager for Charts for Kubernetes. In Helm versions <=3.20.1 and <=4.1.3, a specially crafted Chart will cause helm pull –untar [chart URL | repo/chartname] to write the Chart's contents to the immediate output directory (as defaulted to the current working directory; or as given by the –destination and –untardir flags), rather than the expected output directory suffixed by the chart's name.
