feat(puml): cleanup url, make notes about svg determinism

NOTES.md

@@ -9,6 +9,11 @@ We use a git commit hook to automatically rebuild `.svg` files from plantuml
 sources. The magic of git hooks means that no extra work is required by you
 after creating or editing a `.puml` file
 
+Behind the scenes, this hook spins up a docker container to run the PUML server
+and calls `./scripts/_render_svg.js` for each file that has changed. We use the
+docker version instead of the public puml server to (1) get around rate limits, and
+(2) ensure deterministic SVG output that is git diffable.
