The wiki needs a contribution meta-guide #413

Problem

Players can play a significant amount of hackmud without ever interacting with the infrastructure that the hackmud wiki uses to add new contributions (GitHub, GH actions, PR etiquette etc.) - we need a guide to get them up to speed.

Context

We'd be basically doing a "GitHub 101" page (probably for a new meta-guides category):

• What is git/version control?
• How does Docusaurus use our markdown?
• How do I fork the repo?
• How do I change the content?
• How do I make a PR?
• What is this 'CLA'? Why am I signing away my soul?
• When will my request get merged? What are the criteria for a successful merge?

Worth deciding also if we want to promote codespaces, local copies or both
