Basing this action on push to `chart-*` tags doesn't work: the action itself
creates the new release tag, so trying to push the changes to a tag ends up
with the releaser comparing the changes to themself (and failing).
This also renames the chart from "descheduler" to "descheduler-helm-chart", to
avoid confusion with automated releases.
