Integrate Helm Chart into our release procedure

[ilyakooo0]

We have the helm charts published in the gh-pages branch. It is updated manually and out of sync with the release of Octopod itself.

We need to either:

1. Integrate the helm chart release into our release checklist: https://github.com/typeable/octopod/blob/master/Release_checklist.md
2. Or (more preferable), automate the whole Helm Chart release in our release job:
   

   octopod/.github/workflows/build.yaml
