Checklist:

• I have update the chart version in Chart.yaml following Semantic Versioning.
• Any new values are backwards compatible and/or have sensible default.
• I have followed the testing instructions in the contributing guide.
• I have signed the CLA and the build is green.
• I will test my changes again once merged to master and published.

Changes are automatically published when merged to master. They are not published on branches.

I'll update the chart versions once the content changes are deemed acceptable (and probably squash). I leave commits as distinct while reviewing because otherwise things get really painful.

Thanks! Have you looked at the failing CI, I think just fixing the semantic part is OK by me - doesn't seem like any of this Should fail the other CI
