[repo] update CI for Helm 3

Upgrade CI actions for use with Helm 3.

The chart-testing action changed significantly in its 2.0.0 release and
the workflow is almost completely new. The revision is mostly their
current example:
https://github.com/helm/chart-testing-action/tree/v2.0.1#upgrading-from-v1xx

These changes no longer use the config files and exclude the original
timeout override. It doesn't look like we should need that since the
current default is longer than the old override (300s vs 200s).
