[Feature-request] Please add an template to use GitHub Actions

[Napolitain]

Reason: easy and safe deployment

This repository had the cool idea to use GitHub Actions to deploy (by generating images in the special repository). https://github.com/lowlighter/metrics

I think its very sexy way of "self" hosting the service.

I've done this at https://github.com/nathanchu/github-readme-stats-action. You could use the demo code at https://github.com/nathanchu/github-readme-stats-action-demo/blob/main/.github/workflows/main.yml. I'm still actively working on it so it might be a little buggy and things may break, but you can try it if you want.
