- This diagram was really old and didn't reflect the current practices
(a lot more things are automated now, hurray).
- Anything we replace it with will get outdated fast too.
- Also delete the diagramming docs since I don't believe we have made
another diagram since this one which got out of date and forgotten
about since it was a DrawIO SVG and not easily editable as code.
- If we want diagrams these days, we can use Mermaid which is
diagrams-as-code.
- Add flowchart for handling ready-to-merge pull requests
- Add diagram guidelines
Many thanks to Sean Molenaar for the idea and initial version of the
chart.
