Add Helm chart publishing Github action and instructions on how to configure a naive Helm chart

For services that are going to be published as containers, we may also want to configure a github action to validate, lint, version and publish the Helm chart, with best practices and standards.

Note that I think the creation of the Helm chart should be left to `helm create`

首先檢查此範本如何表示 GitHub Actions 和服務設定，然後使用 `helm create` 作為樸素 chart 設定的參考。定義驗證、lint、版本管理和發布工作流程以及設定說明；當該 action 和文件化的設定支援容器化服務 chart 時，即表示完成。
