Set the chart's placeholder version to 0.41.2

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 3a96b20 (0.41.1) and 065b557 (0.41.0) before it, because a
tree heading for v0.41.2 that still says 0.41.1 tells its reader
something false.
