Using ChartPress for releases with GitHub Actions

[manics]

I thought I'd let you know what I've been doing with Chartpress. Originally I planned to use it to publish a repo with multiple independently versioned Helm Charts with Travis following a similar process to Z2JH, but for releases only, then moved on to the idea of automating tagging based on when the Chart release version was changed.

I wasn't entirely happy with giving Travis full push access to a GitHub repo, then remembered I've got beta access to GitHub Actions so thought I'd try that out.

The result is master...manics:devel
The target repo is https://github.com/manics/kubernetes-omero

Since it's heavily modified for my own workflow I thought I'd mention it instead of opening PRs, but if you see something useful I'm happy to modify it if necessary to get it into this repo.

@manics we now how #134 in chartpress that I remember was a fix you included as well in your fork.

What is the current status of your fork? Do you have suggestions on things to upstream that can be raised for consideration?
