Backup a Github/dwyl Repo to Gitea!

Our original reasoning for this project is still very much still a reality.

GitHub still has regular "incidents": https://www.githubstatus.com/history where it's offline for hours ... ⏳

Using GitHub as our [Single source of truth](https://en.wikipedia.org/wiki/Single_source_of_truth) means it's "mission critical" and we need access to it pretty much _always_.

At present this project mirrors issue data to **`AWS S3`** and @RobStallion asked a very valid question about it: #126
That's _OK_ as a "cold" _backup_ but it's not very useful for business continuity.
