- 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- Anything we replace it with will get outdated fast too.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another diagram since this one which got out of date and forgotten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.
- It's always a pain to re-number everything when adding or removing
steps, so let's use the Markdown numbering trick.
- This does render correctly in HTML, I tested building the site.
- Add the same macOS `--build-from-source` default prefix behaviour
now we have ~4000 linuxbrew-core bottles.
- Merge remaining useful linuxbrew-core-Maintainer-Guide into
Homebrew-homebrew-core-Maintainer-Guide
- Don't special-case linuxbrew-core any more in docs
