Update the "pre-flight" checklist for the new Weaver #620

https://assemblyline.suffolklitlab.org/docs/get_started/project_management

• It's probably a little outdated with the new Weaver and authoring tools
• Incorporate anything worth keeping from the GitHub project template launch card and internal review card
• Items should be in sentence case

Also update links to the project board template to this page. (Here's one.)
