Part of #1417

To follow idea from #1417 (comment)

Not fully tested yet, the ci scripts (date, sed...) are very linux centric so my mac can't run them as-is (I might look into https://github.com/nektos/act, but I'd prefer a granular action to try only parts of those scripts, I wouldn't want to create a commit, issue, etc.

Woah, that's a really good idea, thanks! Let me know when you're done so I can review it :)

I considered linking to github.dev (the direct editor from within the browser), but I decided against because it makes it less likely that newcomers read the contribution guidelines.

So I kept the links closer to the original content.

In the long run there could be a script running to add how many pull requests we had etc but I won't go that far yet.
