Add timestamp to Documentation

[ckartik]

Kind of a nit ask, but would it be possible to add a timestamp to some of the articles and tutorials that are created in the documentation?
Sometimes new things pop into sections like these: https://docs.minaprotocol.com/zkapps/advanced-snarkyjs/events and I'm curious when they were added/updated! 😄
