Suggest to add provenance for tutorials

Suggest to add date last updated and author for tutorials.

Yes I agree; many tutorials have a badge, and a list of contributors like

https://oboacademy.github.io/obook/lesson/chatgpt-ontology-curation/?h=chat

The "last updated" can be taking from the git history I think.

How would you do / enforce this? PR requirement checklist? Let alone retroactively fill this in..

[twhetzel]

Ok, I will add a Contributors section to my tutorial and a Last Updated line (at the top so it's clear to anyone simply reading the content).

Perhaps going forward, tutorial submitters can be encouraged to add these details or perhaps some GH Action to look for some required fields in a tutorial.
