Update SUMMARY.md

[crusso]

Moritz asked me to review the content so I took the liberty of opening a PR to suggest additional sections.
These are just suggestions.

I'd also consider moving subtyping and generics much earlier, since they will be needed for using much of the base library.

Bounds on generic type parameters, if mentioned at all, can go in the advanced section.

Having written some doc before, I strongly advise putting as many examples as possible into separate files, included from the main document, so you can check them with a script. Or find some tool that extracts the snippets from the md files. Then you can use a simple script or Makefile to check the examples.

Feel free to copy the docusaurus setup from the motoko repo if that helps. It adds some mdx libs that let you do file inclusion and makes many examples runnable on the page (when run in preview mode) via the Motoko javascript interpreter, moc_js.

Will look into this

While we're at it:
Should we add ''labeled loops, (null) breaks, do blocks, option blocks"?
