pkg-export-helm: No version & release in the chart name
pkg-export-helm: No version & release in the chart name

Not only it is a convention in the Helm world to not version the chart
name (which is supposed to be exactly the same as the name of the source
chart directory), we'll end up with two version numbers in the package
created by `helm package` command if we have version in the chart name.
