Set the chart's placeholder version to 0.39.0

Cosmetic: make helm-package passes --version and --app-version from the
tag, so these two fields decide nothing about what gets published. Still
done, as with 584d344 (0.38.0) and df83adf (0.37.2) before it, because a
tree heading for v0.39.0 that still says 0.38.0 tells its reader
something false.
