Set the chart's placeholder version to 0.35.1

Cosmetic, as before (497086c, 4358e84): make helm-package passes
--version and --app-version from the tag, so this decides nothing
about what gets published. Kept in step so the tree heading for
v0.35.1 doesn't say 0.35.0 to a reader who hasn't yet seen the tag.
